Audio T Verdict
The Wharfedale SW-10 is a useful middle ground for anyone who wants proper low-frequency reinforcement without committing to a huge subwoofer. Its 250mm long-throw driver is backed by a built-in 200W amplifier, giving it enough authority for home cinema while remaining manageable enough to integrate into a two-channel music system.
The important word here is integration. A good subwoofer should not simply add a layer of boom underneath everything else. The SW-10 gives you adjustable volume, a 30–150Hz crossover, phase inversion and both stereo line-level and dedicated LFE connectivity, so it can be tuned to work with compact standmounts, floorstanding speakers or a multichannel AV system.
Wharfedale also gives the SW-10 useful headroom, with 350W peak amplifier output and an average maximum output figure of 110dB at one metre. It is therefore capable of adding genuine weight to films and music, but the best results come from resisting the temptation to turn it up too far. Get the crossover, level, phase and room position right and the SW-10 should sound like your main speakers have simply discovered another octave rather than like a separate box has started thumping in the corner.
Wharfedale SW-10 Active Subwoofer
The Wharfedale SW-10 is a powered 250mm subwoofer designed to extend the low-frequency performance of stereo hi-fi and home cinema systems.
It combines a long-throw bass driver with its own 200W internal amplifier, adjustable low-pass crossover, level control, phase inversion and automatic signal sensing.
Stereo RCA and dedicated mono LFE connectivity allow it to work with suitable stereo preamplifiers, integrated amplifiers with subwoofer outputs, AV receivers and surround processors.

What Does a Subwoofer Actually Do?
A subwoofer is designed to reproduce low frequencies that the main speakers either cannot reproduce at all or begin to reproduce with reduced output.
That does not mean its only purpose is explosions, thunder and exaggerated bass effects.
In a music system, low-frequency extension can contribute to:
- The body of bass guitar
- Kick-drum weight
- The lower registers of piano
- Double bass
- Electronic low frequencies
- Organ notes
- The acoustic scale of a recording venue
In home cinema, the subwoofer can additionally reproduce the dedicated Low Frequency Effects or LFE channel contained within compatible multichannel soundtracks.
Not Just More Bass
A properly adjusted subwoofer should extend the system rather than dominate it.
If you can constantly point to one corner of the room and say, "the bass is coming from that box", the level or crossover is often set too high, the position may be unsuitable or the phase relationship may need attention.
When integration is right, switching the subwoofer off can often reveal what it had been contributing more clearly than switching it on.
For more background on using a subwoofer for music, read the Audio T guide No Substitute for a Subwoofer - It's Not Just Thump.
250mm Long-Throw Bass Driver
The SW-10 uses a single 250mm or ten-inch long-throw driver.
A subwoofer needs to move considerably more air than a conventional midrange or treble driver because low frequencies require substantial diaphragm displacement.
Why a 10-Inch Driver?
A 250mm cone provides a useful balance between physical size and radiating area.
It is large enough to move meaningful volumes of air for music and film soundtracks without creating the cabinet dimensions associated with Wharfedale's larger SW-12 and SW-15 models.
Long-Throw Design
"Long throw" refers to the driver's ability to move forwards and backwards through relatively large excursions.
This helps the SW-10 generate useful low-frequency output from a cabinet that remains practical for an ordinary domestic room.
Non-Pressed Paper Cone
Wharfedale uses a non-pressed paper diaphragm in the SW Series.
The manufacturer chose the material for a combination of structural rigidity and self-damping, helping the cone move substantial quantities of air while limiting unwanted resonant behaviour.
Why Self-Damping Matters
A bass cone should start and stop as accurately as possible in response to the incoming electrical signal.
If the diaphragm continues ringing after the signal has changed, bass can lose definition and individual notes can become harder to distinguish.
Copper-Lined Centre Vent
Wharfedale also uses copper around the driver's centre vent.
This is intended to reduce magnetic distortion while improving heat dissipation from the motor assembly.
Heat Management
A subwoofer driver converts electrical energy into physical movement, but some energy inevitably becomes heat.
Managing that temperature is important when the subwoofer is reproducing demanding bass passages for extended periods.
Built-In 200W Amplifier
The SW-10 contains its own 200W power amplifier.
This means your stereo amplifier or AV receiver does not directly supply the electrical power needed to drive the 250mm bass unit.
Why Is the Subwoofer Active?
Low-frequency reproduction requires significant power and the amplifier can be optimised specifically for the driver and cabinet it controls.
Putting the amplifier inside the subwoofer also means the source equipment only needs to provide a low-level audio signal through the appropriate RCA connection.
350W Peak Output
Wharfedale specifies a peak amplifier output of 350W.
Peak output describes short-term headroom rather than continuous power delivery.
This additional reserve can be useful with sudden low-frequency transients such as kick drums, cinematic impacts and electronic bass effects.
110dB Average Maximum Output
The SW-10 is specified for an average maximum output of 110dB at one metre.
This gives it substantial potential output for a domestic subwoofer of this size.
That does not mean it should routinely be operated anywhere near maximum output. The goal is controlled extension and system integration, not simply producing the largest possible sound-pressure number.
40–120Hz Frequency Response
Wharfedale specifies the SW-10's frequency response as 40Hz to 120Hz within +/-3dB.
The subwoofer is therefore designed to operate beneath the main speaker range rather than reproducing midrange frequencies.
Does 40Hz Mean It Produces Nothing Below 40Hz?
No.
A quoted +/-3dB frequency-response range identifies the manufacturer's specified operating band within that tolerance. Acoustic output does not suddenly disappear immediately outside it.
Actual low-frequency behaviour in your listening position will also be strongly influenced by room dimensions and placement.
Room Gain
Walls and corners can reinforce low frequencies.
This means a subwoofer may produce a different measured and perceived bass balance in a normal room from the result obtained under controlled measurement conditions.
30–150Hz Adjustable Crossover
The rear crossover control lets you choose where the SW-10 begins rolling away as frequencies rise.
The available adjustment range runs from 30Hz to 150Hz.
Why Is the Crossover Important?
The aim is to create a smooth handover between the main speakers and the subwoofer.
If the SW-10 is crossed too low with small speakers, neither the main speakers nor the subwoofer may reproduce part of the bass range strongly enough, creating a noticeable gap.
If the crossover is set unnecessarily high with large speakers, both may reproduce too much of the same upper-bass region, making the system sound thick or bloated.
Small Speakers Usually Need a Higher Crossover
Wharfedale's own setup guidance recommends using higher crossover settings with smaller bookshelf speakers and lower settings with larger floorstanders. Treat that as a starting principle rather than assuming one frequency is correct for every system.
Should I Just Set It to 80Hz?
Not automatically.
80Hz is a common bass-management point in home cinema, but the optimum setting depends on the main speakers, AV receiver, room and whether the receiver or the SW-10 itself is performing the filtering.
Stereo Hi-Fi Crossover Setup
In a stereo system, start by understanding how low your main speakers reproduce cleanly.
The goal is then to bring the SW-10 in gradually beneath them rather than allowing the subwoofer to duplicate a large amount of their bass output.
Home Cinema Crossover Setup
With a modern AV receiver, the receiver will often perform the main bass-management crossover digitally.
Follow the AV receiver's setup procedure and room-calibration guidance where available.
Dedicated LFE Input
The SW-10 provides a mono RCA LFE input for use with a compatible AV receiver or surround processor.
This is normally the simplest connection when the system includes a dedicated subwoofer output.
What Is LFE?
LFE stands for Low Frequency Effects.
In a multichannel soundtrack, the ".1" in 5.1 or 7.1 refers to a dedicated low-frequency effects channel routed to a subwoofer through the AV processor's bass-management system.
Connecting to an AV Receiver
Use a screened RCA subwoofer cable between the AV receiver's Subwoofer Out or LFE output and the SW-10's mono LFE input.
The cable can be relatively long, which makes proper screening useful for minimising unwanted hum and interference.
Browse Home Cinema Amplifiers and AV Receivers at Audio T.
Stereo RCA Line Inputs
The SW-10 also includes separate left and right RCA line-level inputs.
These allow integration with stereo equipment providing suitable preamplifier or stereo subwoofer outputs.
Using a Stereo Pre-Out
If your amplifier provides a spare variable preamplifier output or dedicated stereo subwoofer output, the left and right RCA inputs can be used.
Because different amplifiers provide different connection options, check the amplifier manual before connecting.
Pre-Out / Main-In Amplifiers
Wharfedale's manual also describes integration with suitable amplifiers where the preamplifier and power-amplifier sections can be separated.
This arrangement uses screened RCA cables and suitable Y adaptors to feed both the main amplifier and the SW-10.
No Speaker-Level Input
The SW-10's published connections are line-level RCA and LFE. Do not connect normal amplified loudspeaker outputs directly to these RCA sockets. If your amplifier has no suitable line-level output, speak to Audio T about an appropriate subwoofer or connection method.
200mV Input Sensitivity
Wharfedale specifies 200mV line-input sensitivity for maximum output.
The stereo line input has a 10kO impedance, while the dedicated LFE connection is specified at 5kO.
Phase Inversion
A 0° / 180° phase switch helps align the SW-10 acoustically with the main loudspeakers at the listening position.
What Does Phase Do?
The main speakers and subwoofer are reproducing overlapping parts of the low-frequency spectrum.
If their acoustic outputs arrive at the listening position with an unfavourable phase relationship, they can partially cancel rather than reinforce one another.
How Do I Set Phase?
Wharfedale recommends starting at 0°.
Play familiar music containing extended bass and compare the result with 180°.
Choose the setting that produces the most natural, extended and well-defined bass at the normal listening position.
Don't Choose Phase by Standing Next to the Subwoofer
The interaction you are trying to optimise occurs at the listening position. Make the comparison from your normal seat rather than leaning over the control panel.
Adjustable Volume
The SW-10 has its own level control.
This determines how strongly the subwoofer contributes relative to the main system when its local volume control is being used.
How Loud Should a Subwoofer Be?
Usually less loud than people initially expect.
Wharfedale specifically advises that bass should sound like a natural extension of the main loudspeakers.
Setting the level too high can swamp the music, reducing clarity and definition.
The "Turn It Down Until You Miss It" Approach
A useful stereo setup technique is to begin with the subwoofer clearly audible and gradually reduce its level until it no longer attracts attention to itself.
Switch it off temporarily. If the system suddenly sounds smaller, lighter and less complete, but you could not obviously hear "a subwoofer" while it was operating, integration is moving in the right direction.
Auto Sense Power
The SW-10 includes automatic signal sensing.
With Auto Sense enabled, the amplifier activates when an audio signal is detected at the input.
If no signal is detected for around 20 minutes, the SW-10 enters a reduced-power mute state.
Can Auto Sense Be Disabled?
Yes. Wharfedale provides a switch so the automatic function can be disabled if preferred.
Switch Off During Long Periods of Non-Use
For extended periods when the system will not be used, Wharfedale recommends switching the subwoofer off rather than leaving it permanently active.
Subwoofer Placement
Subwoofer positioning can make an enormous difference because low frequencies interact strongly with the dimensions and boundaries of the room.
Wharfedale suggests beginning towards the front of the listening area and roughly 200mm from a wall.
Start Around 200mm From the Wall
This is a sensible initial position rather than a strict rule.
From there, experiment by moving the SW-10 while listening from the main seating position.
Closer to a Wall Means More Bass
Moving the subwoofer closer to a solid wall normally increases low-frequency reinforcement.
This can be useful where output feels a little light, but too much reinforcement can reduce definition.
Corner Placement Gives Even More Reinforcement
Putting a subwoofer into a corner adds reinforcement from multiple boundaries.
Wharfedale specifically notes that this can increase bass further but may do so at the expense of clarity.
If the Bass Is Boomy
Try:
- Reducing the subwoofer level
- Moving it away from the corner
- Moving it further from the rear wall
- Checking the crossover setting
- Comparing the phase positions
- Reviewing AV receiver bass-management settings
If the Bass Is Too Weak
Check:
- The subwoofer is powered on
- Auto Sense has detected the signal
- The RCA cable is connected correctly
- The AV receiver has its subwoofer output enabled
- The local volume is not too low
- The crossover has not been set too low
- The phase switch is in the better position
- The room position is not producing a cancellation at the listening seat
The Subwoofer Crawl
Rooms can create peaks and dips in bass response, so the position that looks most obvious is not always the one that sounds most even.
One practical approach is to temporarily position the subwoofer near the main listening location, play steady bass-rich material and move around likely subwoofer positions listening for places where the bass sounds even and controlled.
You can then try the subwoofer in those positions and assess the result from the normal seat.
Keep It Away From Rattling Objects
A powerful low-frequency system can excite furniture, doors, ornaments and loose floorboards.
Wharfedale recommends avoiding surfaces or nearby objects likely to rattle.
Make Sure the Floor Is Stable
The SW-10 weighs 15kg and should sit squarely and securely.
A solid, stable floor makes it easier to prevent unwanted mechanical movement and rattles.
Levelling the SW-10
Before making final connections, Wharfedale recommends checking that the subwoofer sits squarely on all of its floor contacts.
If it rocks, stabilise it before completing the setup.
Protect Hard Floors
Where the supplied floor interface could mark timber, laminate, tile or another delicate surface, use suitable protective cups or discs.
Music or Home Cinema?
The SW-10 is designed for both.
Stereo Hi-Fi
- Extends bass beneath the main speakers
- Useful with compact standmounts
- Can complement floorstanders too
- Stereo RCA connectivity
- Adjustable crossover and phase
- Best when integrated subtly
Home Cinema
- Dedicated mono LFE input
- Reproduces redirected bass
- Supports the .1 soundtrack channel
- 350W peak amplifier output
- 110dB average maximum output
- Works with AV receiver calibration
Why Add a Subwoofer to Standmount Speakers?
Compact standmount speakers often trade low-frequency extension for smaller cabinets and easier room placement.
A subwoofer lets the system regain some of that missing foundation without replacing the main speakers.
The SW-10's variable crossover is particularly useful here because smaller speakers can normally be partnered with a higher crossover point than large floorstanders.
Can I Add SW-10 to Floorstanding Speakers?
Yes.
Floorstanding speakers do not automatically reproduce every low frequency contained in music or film soundtracks.
The SW-10 can be crossed lower so that it only contributes beneath the region the main speakers already reproduce convincingly.
Why Add a Sub to Speakers That Already Have Good Bass?
The objective can be extension rather than simply greater quantity.
A floorstander may sound powerful at 50Hz yet begin rolling away before reaching the deepest information in a recording.
A correctly integrated subwoofer can underpin that lowest region without changing the tonal character of the main speaker through the rest of the spectrum.
Subwoofer Integration With Wharfedale Diamond Speakers
The SW-10 can be used with passive Wharfedale speakers such as the Diamond range provided the amplifier or AV receiver offers suitable subwoofer connectivity.
The exact crossover setting should be chosen according to the specific speaker model rather than assuming every Diamond speaker needs the same value.
Subwoofer Integration With Wharfedale Heritage Speakers
Large Heritage speakers such as LINTON already reproduce substantial low-frequency energy, so an SW-10 would normally be crossed considerably lower than when partnered with compact satellites or bookshelf speakers.
The goal would be extending the lowest bass rather than making an already full-bodied speaker simply sound heavier.
Can SW-10 Work With Other Speaker Brands?
Yes.
A subwoofer does not need to carry the same badge as the main speakers.
Connection compatibility, room size, available output and successful crossover, level and phase integration are more important.
SW-10 or SW-12?
The next model in Wharfedale's SW Series is the SW-12.
SW-10
- 250mm / 10-inch driver
- 200W amplifier
- 350W peak output
- 40–120Hz response
- 110dB average maximum output
- 336mm cabinet width
- 15kg
- More manageable domestic footprint
SW-12
- 300mm / 12-inch driver
- 300W amplifier
- 450W peak output
- 35–120Hz response
- 118dB average maximum output
- 395mm cabinet width
- 22.1kg
- Greater output and deeper extension
Who Should Choose SW-10?
SW-10 makes particular sense when:
- The room is small or medium sized
- You want a more manageable cabinet
- You are adding bass to standmount speakers
- You want music and home cinema versatility
- You do not require the maximum output of a 12-inch or 15-inch model
- Budget and space both matter
Who Should Consider SW-12?
Move up to the larger model if:
- The room is larger
- You sit further from the subwoofer
- You listen at higher levels
- Home cinema impact is a major priority
- You want deeper published extension
- The larger cabinet fits comfortably
SW-10 or SW-15?
The SW-15 sits considerably further up the range, using a 380mm / 15-inch driver and a much more powerful amplifier.
It is intended for systems requiring substantially greater low-frequency output and is physically much larger.
Bigger Isn't Automatically Better
A larger subwoofer may offer greater output and extension, but the correct choice depends on the room and how loud the system actually needs to play.
A properly positioned and well-integrated SW-10 can be a much better choice than an oversized subwoofer permanently turned down because the room cannot accommodate its output.
Using Two Subwoofers
Some systems can benefit from two subwoofers, particularly where room modes create large differences in bass response between seating positions.
Whether dual-subwoofer operation is appropriate depends on the available processor outputs, room, placement and calibration capabilities.
Is Two Subs About Twice as Much Bass?
Not necessarily.
One of the main reasons to use multiple subwoofers is to achieve more even low-frequency coverage around a room rather than simply turning the bass level up.
Using SW-10 With an AV Receiver
A typical setup uses a single screened RCA cable from the AV receiver's subwoofer output to the SW-10 LFE input.
After connecting:
- Enable the subwoofer in the AV receiver's speaker configuration.
- Set the other speakers' bass-management settings appropriately.
- Run the receiver's automatic calibration where available.
- Check the resulting speaker distances and levels.
- Listen to familiar programme material.
- Fine-tune the subwoofer level if required.
What If My AV Receiver Has Two Subwoofer Outputs?
You can use one output for a single SW-10.
Where the receiver supports independent dual-subwoofer calibration, a second compatible subwoofer can potentially be added later.
Using SW-10 With Stereo Hi-Fi
Stereo integration depends on the outputs available from your amplifier.
Suitable options can include:
- Dedicated stereo subwoofer outputs
- Variable preamplifier outputs
- Pre-out / main-in arrangements compatible with Wharfedale's published connection method
If your amplifier offers none of these, do not assume the speaker terminals can be wired directly into the SW-10's RCA sockets.
Can I Connect It to a Turntable?
Not directly.
A turntable first needs the appropriate phono amplification and system volume control. The SW-10 then receives a suitable variable line-level signal from the amplification system.
Can I Connect It to a CD Player?
Normally the CD player feeds the stereo amplifier, and the amplifier provides the appropriate variable output to the subwoofer.
Connecting a normal fixed-level CD output straight to a powered subwoofer would not provide conventional coordinated system volume control.
Can I Use It With a Streamer?
Yes, provided the overall system supplies a suitable controlled line-level or subwoofer output.
Many modern streaming amplifiers provide dedicated subwoofer connectivity, making integration straightforward.
Signal-to-Noise Ratio
Wharfedale specifies the SW-10 at a signal-to-noise ratio of at least 85dB.
Proper cable routing and screened RCA connections remain important because low-level analogue connections can pick up hum if they are poorly installed.
Avoid Mains Hum
If the subwoofer produces an unwanted hum:
- Check that the RCA cable is fully inserted
- Use a properly screened cable
- Keep signal cables away from mains leads where practical
- Disconnect unnecessary signal connections temporarily to identify the source
- Consult your Audio T store if the cause is unclear
Dimensions
Wharfedale publishes the SW-10 dimensions as:
- Main cabinet height: 358mm
- Foot allowance: 58mm
- Approximate overall height: 416mm
- Width: 336mm
- Main cabinet depth: 366mm
- Rear allowance: 15mm
- Approximate overall depth: 381mm
- Net weight: 15kg
Measure the Space Properly
When planning an installation, don't use the main cabinet dimensions alone.
Allow additional space for:
- The supplied floor interface
- RCA plugs
- The IEC mains cable
- Access to controls and power switch
- Air circulation
- Moving the cabinet during setup
15kg Cabinet
The SW-10 weighs 15kg.
Its mass helps provide a stable platform for the long-throw driver and amplifier but means it should be lifted carefully rather than dragged across delicate flooring.
Blackwood and White Sandex
Audio T currently lists Blackwood and White Sandex versions of the SW-10.
Wharfedale's wider manufacturer specification also references Rosewood and Walnut Pearl finishes, although availability can differ by market and production period.
High-Gloss Front Baffle
Wharfedale combines its cabinet finishes with a contrasting high-gloss front baffle, helping the SW Series coordinate visually with a wide variety of stereo and home cinema speakers.
Power Connection
The SW-10 includes an IEC mains input and requires mains electricity because the amplifier is built into the cabinet.
Before connecting it, make sure the voltage shown on the amplifier panel is appropriate for your mains supply.
Switch Off Before Changing Connections
Wharfedale specifically advises switching off the subwoofer and the rest of the system before making or changing audio connections. Keep the mains connection accessible and do not expose the unit to moisture.
Initial Setup
A sensible first setup is:
- Position the SW-10 roughly 200mm from a wall.
- Make sure it sits firmly and does not rock.
- Switch off the complete system.
- Connect the appropriate RCA or LFE cable.
- Connect the supplied IEC mains lead.
- Set the subwoofer volume to minimum initially.
- Set phase to 0°.
- Choose a sensible starting crossover for the main speakers.
- Switch on the source system and subwoofer.
- Play familiar programme material containing extended bass.
- Increase the subwoofer level gradually.
- Stop before the bass begins dominating the main speakers.
- Compare 0° and 180° phase.
- Fine-tune the crossover.
- Experiment with room position if bass remains uneven.
Recommended SW-10 Stereo Setup Routine
- Check that your amplifier provides a suitable variable line-level output.
- Use a properly screened RCA cable.
- Place the subwoofer towards the front of the listening room initially.
- Begin around 200mm from a rear wall.
- Avoid a corner as your automatic first position.
- Start with phase at 0°.
- Set the local level low.
- Choose a crossover appropriate to the main speakers.
- Play a familiar recording with consistent bass.
- Bring the subwoofer level up until the system gains weight.
- Reduce the level if the SW-10 becomes obviously identifiable.
- Compare the 180° phase setting.
- Choose the phase position with the most natural extension.
- Fine-tune the crossover in small steps.
- Check several recordings rather than using one bass-heavy track.
- Temporarily switch the subwoofer off to judge what it is contributing.
- Move the SW-10 if room boom or cancellation remains obvious.
- Recheck level after changing position.
Recommended SW-10 Home Cinema Setup Routine
- Position the SW-10 towards the front of the room.
- Leave access to the rear controls and mains connection.
- Switch the AV receiver and subwoofer off.
- Connect the receiver's Subwoofer Out to the SW-10 LFE input.
- Use a screened RCA subwoofer cable.
- Connect the IEC mains lead.
- Enable the subwoofer in the AV receiver's setup menu.
- Configure the other speakers' bass management appropriately.
- Run automatic room calibration where available.
- Check that the measured speaker and subwoofer distances are plausible.
- Check channel levels.
- Listen to familiar dialogue and effects.
- Check that bass has impact without overwhelming voices.
- Move the SW-10 away from corners if bass sounds excessively heavy.
- Fine-tune the receiver's subwoofer level rather than immediately turning the SW-10 to maximum.
- Re-run calibration after substantial position changes.
Cleaning and Maintenance
Wharfedale recommends cleaning the cabinet only with a soft dry cloth.
Avoid spray polish, liquids and aggressive cleaning products.
The bass driver should not be touched during cleaning.
Cleaning the Grille
Wharfedale advises using a soft brush rather than a vacuum cleaner on the grille.
If you need to clean underneath the cabinet, switch the SW-10 off, disconnect it from the mains and lift it clear before moving it.
Keep the Original Packaging
A 15kg powered subwoofer is much safer to transport in its purpose-designed original packaging.
Keeping the carton and internal packing is sensible if you move house, change system or ever need the unit serviced.

Is the 350W figure continuous?
No. Wharfedale separately specifies 200W amplifier output and 350W peak output.
How loud can the SW-10 play?
Wharfedale specifies an average maximum output of 110dB at one metre.
What is the frequency response?
40Hz to 120Hz within +/-3dB.
Does that mean it stops completely below 40Hz?
No. The figure describes the manufacturer's specified response within the quoted tolerance rather than an absolute cutoff.
What is the adjustable crossover range?
30Hz to 150Hz.
Why is the crossover adjustable?
It allows the subwoofer to be blended with main speakers of different sizes and low-frequency capabilities.
What crossover should I use?
There is no single correct figure. Smaller main speakers generally require a higher crossover, while large floorstanders can usually be crossed lower.
Should I use 80Hz?
80Hz can be a useful home cinema starting point, but follow the AV receiver's calibration and the capabilities of your speakers rather than treating it as mandatory.
Does the SW-10 have an LFE input?
Yes. It has a dedicated mono RCA LFE input.
Does it have stereo inputs?
Yes. There are left and right RCA line-level inputs.
Can I connect it to an AV receiver?

Is a subwoofer only for action films?
No. Bass extension is also relevant to music, including bass guitar, drums, piano, organ and electronic instruments.
Does the SW-10 have a volume control?
Yes.
How high should the volume be?
Set it so the bass sounds like a natural extension of the main speakers rather than an obviously separate sound source.
What happens if I set it too high?
Bass can dominate the system and reduce clarity and definition.
Does the SW-10 have phase adjustment?
Yes. It provides 0° and 180° phase settings.
Which phase setting should I use?
Start with 0° and compare 180° from the listening position. Use the setting that gives the most natural and extended bass.
What does phase affect?
It changes the relationship between the subwoofer's low-frequency output and that of the main speakers at the listening position.
Does it have automatic power switching?
Yes. Wharfedale calls the function Auto Sense.
How does Auto Sense work?
The amplifier activates when it detects an incoming signal and enters a reduced-power state after approximately 20 minutes without a signal.
Can Auto Sense be switched off?
Yes.
Should I leave the SW-10 on all the time?
Auto Sense is convenient for everyday use, but Wharfedale recommends switching it off during extended periods of non-use.
Where should I place the SW-10?
Wharfedale recommends beginning towards the front of the room and around 200mm from a wall, then experimenting according to the bass response.
Can it go against a wall?
Yes, but moving closer to a wall normally increases bass output.
Can it go in a corner?
Yes, but Wharfedale notes that corner placement can increase bass at the expense of clarity.
Why is the bass boomy in the corner?
Low frequencies are being reinforced by several room boundaries at once.
What should I do if the bass is too strong?
Reduce the level, move the SW-10 away from corners or walls and check the crossover and phase settings.
What should I do if the bass is weak?
Check the signal connection, level, crossover, phase and room position, together with the AV receiver's subwoofer settings where applicable.
Can room position really make that much difference?
Yes. Low-frequency room modes can create substantial peaks and cancellations depending on the position of both the subwoofer and listener.
Can I put the SW-10 behind the sofa?
It may work acoustically, but test the position carefully. A front-of-room position is Wharfedale's recommended starting point.
Can I hide it inside a cabinet?
We would not recommend enclosing a powered subwoofer tightly inside furniture. It needs stable placement, access to its controls and mains connection, and freedom from nearby rattling surfaces.
Will it make furniture rattle?
Strong low frequencies can excite loose objects and furniture. Wharfedale specifically recommends avoiding nearby surfaces or objects that may rattle.
How much does the SW-10 weigh?
15kg.
How wide is it?
336mm.
How high is it?
The main cabinet is 358mm high, with Wharfedale adding 58mm for the feet, giving approximately 416mm overall.
How deep is it?
The main cabinet depth is 366mm plus approximately 15mm rear allowance, or around 381mm overall.
Does it need mains power?
Yes. The SW-10 contains its own amplifier and connects to the mains using an IEC lead.
Is the mains lead included?
Yes. Wharfedale lists an IEC power cord among the supplied accessories.
What is the line-input sensitivity?
200mV for maximum output.
What is the stereo line-input impedance?
10kO.
What is the LFE-input impedance?
5kO.
What is the signal-to-noise ratio?
Wharfedale specifies at least 85dB.
Is SW-10 suitable for standmount speakers?
Yes. Its adjustable crossover allows it to be blended with compact speakers that begin rolling off higher in frequency.
Can it work with floorstanding speakers?
Yes. Use a lower crossover where appropriate so the subwoofer extends rather than unnecessarily duplicates their bass output.
Can it work with Wharfedale Diamond speakers?
Yes, provided the amplification offers appropriate subwoofer connectivity.
Can it work with Wharfedale LINTON?
Yes, although LINTON already reaches deeply in the bass, so careful low crossover and level settings would be especially important.
Can I use it with speakers from another manufacturer?
Yes. Successful integration is more important than matching the brand name.
What is the difference between SW-10 and SW-12?
SW-12 uses a larger 300mm driver, 300W amplifier, 450W peak output and is specified to 35Hz rather than 40Hz within the +/-3dB frequency-response range.
Is SW-12 louder?
Wharfedale specifies 118dB average maximum output for SW-12 compared with 110dB for SW-10.
Which is better for a small room?
SW-10 is the more manageable option and may provide all the output required in a smaller or medium-sized room.
Which is better for a large room?
SW-12 or SW-15 provides greater driver area and maximum output where a substantially larger space needs to be energised.
Can I use two SW-10 subwoofers?
Potentially, if your processor or connection arrangement supports multiple subwoofers and the room benefits from them.
Will two subwoofers give twice as much bass?
The more useful reason for multiple subs is often more even bass coverage across the room rather than simply greater loudness.
Should I run my AV receiver's room correction?
Yes, where available. Run it after the speakers and subwoofer are broadly positioned, then check that its results are sensible.
Should I recalibrate after moving the subwoofer?
Yes after a significant change of position, because the low-frequency interaction with the room will have changed.
Why does bass disappear in my listening chair?
The seating position may coincide with a low-frequency room cancellation. Moving either the subwoofer or listening position can sometimes improve this dramatically.
What finishes does Audio T currently list?
Blackwood and White Sandex.
What finishes does Wharfedale specify?
Wharfedale's broader specification also references Rosewood and Walnut Pearl alongside White Sandex and Blackwood.
How should I clean the cabinet?
Use a soft dry cloth.
Can I vacuum the grille?
Wharfedale advises against it. Use a soft brush instead.
Should I keep the original box?
Yes. It is useful for safely transporting or returning a 15kg powered subwoofer.
Should I audition a subwoofer before buying?
Yes where possible. The correct size and setup depend heavily on the main speakers, room, listening level and whether music or home cinema is the priority.

Why Buy the Wharfedale SW-10 From Audio T?
A subwoofer is one of those products where setup can matter almost as much as the box itself. The wrong level, crossover, phase or room position can make an excellent subwoofer sound slow and overpowering, while a well-integrated one can simply make the whole system sound more complete.
Audio T can help match the SW-10 to your main speakers, amplifier or AV receiver, demonstrate the difference between subwoofer sizes and advise on positioning and bass management. Whether the priority is stereo music, films or a system that handles both, we can help you get the bass working with the room rather than fighting against it.
