Audio T Verdict
The Sonus faber Concertino G4 is a lovely example of how a compact loudspeaker can be made genuinely special without becoming unnecessarily complicated. At heart it remains a simple two-way passive design, but almost everything around those two drivers has been considered with unusual care, from the cork central chassis and ribbed solid-walnut side panels to the plant-based leather covering and phase-coherent crossover.
The result is not a speaker designed around headline sensitivity or huge bass figures. At 85dB and 4O, Concertino deserves a good amplifier, while its 60Hz lower frequency specification tells you that it is still fundamentally a compact standmount rather than a substitute for a large floorstander. What it offers instead is the combination of craftsmanship, natural materials, controlled cabinet behaviour and carefully integrated drivers that defines Sonus faber's Heritage approach.
We would regard the dedicated Iron Stands as the natural partners where space and budget allow. They put Concertino at the intended listening height and create an extraordinarily distinctive complete installation, although they are sold separately. For a smaller or medium-sized room where the loudspeakers themselves are expected to look every bit as special as the rest of the system, Concertino G4 deserves a proper demonstration.
Iron Stands Sold Separately
This listing is for the Sonus faber Concertino G4 loudspeakers only. The dedicated Sonus faber Iron Stands shown in some manufacturer photography are optional and are available separately.
Sonus faber Concertino G4 Speakers
The Sonus faber Concertino G4 is the fourth generation of one of the Italian manufacturer's most recognisable compact loudspeakers.
The original Concertino arrived in 1994. Thirty years later, the G4 revisits that compact two-way philosophy using materials and technologies developed across more recent Sonus faber projects while retaining the trapezoidal proportions, solid wood and craftsmanship associated with the company's Heritage Collection.
Concertino G4 is handmade in Vicenza, Italy and combines solid walnut, cork, brass and a plant-based leather alternative with a D.A.D. Arrow Point soft-dome tweeter and long-throw paper-pulp midwoofer.

Thirty Years of Concertino
The Concertino story began in 1994.
The basic idea was refreshingly simple: create a compact two-way speaker that distilled Sonus faber's approach to natural materials, Italian craftsmanship and musical reproduction into a smaller enclosure.
Concertino G4 arrived in 2024 to mark thirty years since that original model.
Why G4?
G4 identifies this as the fourth generation of Concertino.
That distinction is useful because older Concertino models remain well known on the second-hand market. The current speaker is not a reproduction of one of those earlier designs.
Its drivers, cabinet construction, port arrangement, materials and crossover reflect contemporary Sonus faber engineering.
Heritage Without Standing Still
The Heritage Collection is built around the idea that traditional materials and proportions can coexist with current acoustic engineering.
Concertino G4 therefore retains recognisable Sonus faber ingredients such as solid walnut and a trapezoidal cabinet while introducing cork and a plant-based leather alternative in ways that would not have been possible on the original 1994 speaker.
Made in Vicenza, Italy
Concertino belongs to Sonus faber's Heritage Collection, whose loudspeakers are built by the company's artisans in Vicenza.
This is important because much of the speaker's appeal comes from its physical construction as well as its acoustic design.
A Compact Two-Way Design
Concertino keeps the driver complement simple.
Each cabinet contains:
- One 1.1-inch D.A.D. Arrow Point soft-dome tweeter
- One 5.25-inch long-throw midwoofer
The two drivers meet at 1700Hz.
Why Two-Way?
A two-way loudspeaker has fewer acoustic handovers to manage than a three-way design.
The midwoofer covers the bass and midrange before handing over directly to the tweeter.
This simplicity places considerable importance on the quality of both drive units and the way their outputs integrate around the crossover region.
D.A.D. Arrow Point Tweeter
High frequencies are reproduced by Sonus faber's D.A.D. Arrow Point tweeter.
D.A.D. stands for Damped Apex Dome.
The concept addresses a behaviour found in conventional soft domes, where the centre or apex of the diaphragm can begin moving out of phase at very high frequencies.
By damping that central area, Sonus faber aims to control the unwanted behaviour while retaining the smooth tonal qualities associated with a silk dome.
Why Damp the Dome Apex?
A soft dome does not remain perfectly piston-like across its complete operating range.
At sufficiently high frequencies, different parts of the diaphragm can begin behaving differently.
The D.A.D. system is intended to control that movement at the apex and reduce one cause of early high-frequency roll-off.
1.1-Inch Tweeter
Sonus faber's technical specification gives the Concertino tweeter as 1.1 inches.
You may also see it described more generally as a one-inch silk dome in promotional copy. For the Audio T technical specification, we would use the manufacturer's more precise 1.1-inch figure.
5.25-Inch Long-Throw Midwoofer
The midrange and bass are handled by a single 5.25-inch long-throw driver.
Its diaphragm is based around paper pulp, continuing Sonus faber's long-running preference for natural-fibre-based driver materials.
Why Paper Pulp?
Paper-based diaphragms can combine low mass, useful stiffness and natural self-damping.
That makes the material particularly useful where one driver needs to reproduce both bass and a broad portion of the midrange.
Long-Throw Design
The term long throw refers to the driver's ability to move through useful forward and backward excursion.
This is especially important in a relatively compact speaker because low-frequency output requires moving considerably more air than midrange or treble.
Ferrite Magnet Motor
Sonus faber specifies a ferrite magnet system for the Concertino midwoofer.
The motor assembly converts the amplifier's electrical signal into controlled movement of the voice coil and cone.
Organic Basket
The driver uses what Sonus faber describes as an organic basket.
The structure is shaped to support the moving system while allowing airflow around the rear of the cone rather than unnecessarily obstructing it.
A 1700Hz Crossover
The crossover frequency is 1700Hz.
Below this point, the midwoofer carries the majority of the acoustic load. Above it, the D.A.D. tweeter increasingly takes over.
Phase-Coherent Crossover Philosophy
Sonus faber deliberately keeps the Concertino crossover relatively simple and applies what it calls a phase-coherent philosophy.
The objective is to align the behaviour of the two drive units around their handover so they contribute to a coherent stereo image rather than behaving like two obviously separate sound sources.
Why Phase Matters
A crossover does more than divide frequencies.
Electrical filters also alter phase, so the designer has to consider how the acoustic output of both drivers combines at the listening position.
Good integration is especially important around voices and instruments that contain information spanning both driver ranges.
The Cork Chassis
One of the most unusual parts of Concertino G4 is its central cork structure.
Rather than treating cork merely as a decorative surface, Sonus faber uses it as an acoustic part of the enclosure.
Why Cork?
Cork has useful damping behaviour and can be formed into shapes suited to the internal requirements of the cabinet.
Sonus faber uses it to limit internal resonance while reducing the quantity of conventional damping material required inside the loudspeaker.
A First for a Sonus faber Midwoofer
Concertino G4 marked the first time Sonus faber paired its cork structural technology directly with a midwoofer.
The company had already explored cork elsewhere, including higher-end loudspeaker development, before adapting it to this compact Heritage design.
Reducing Internal Resonance
The rear of a loudspeaker cone generates as much acoustic energy into the cabinet as the front surface sends into the room.
If the internal structure reflects too much of that energy back towards the cone, it can colour the sound.
The cork architecture is intended to help control that internal behaviour.
Less Conventional Damping Material
Because the cork itself provides acoustic damping, Sonus faber can reduce its reliance on additional absorptive material inside the enclosure.
This is not simply a sustainability story. It forms part of the acoustic tuning of the cabinet.
Solid Walnut Side Walls
The cabinet sides are made from solid walnut rather than a conventional wood-effect vinyl wrap.
Walnut is central to the appearance of many Sonus faber Heritage loudspeakers, but its use here is structural as well as decorative.
Ribbed Walnut Construction
The outer walnut surfaces are visibly ribbed.
Sonus faber says this shaping adds structure and rigidity to the cabinet, reducing the need for conventional internal bracing.
Why Cabinet Rigidity Matters
A loudspeaker cabinet should ideally support the drive units without contributing a strong acoustic signature of its own.
Uncontrolled panel vibration can blur bass, colour the midrange and add delayed energy not present in the original signal.
Trapezoidal Cabinet Shape
Concertino retains the historic trapezoidal form associated with earlier Sonus faber designs.
Aside from its visual identity, moving away from a completely rectangular box changes the relationship between opposing internal surfaces and helps the cabinet avoid behaving like a simple parallel-sided enclosure.
Plant-Based Leather Alternative
Concertino G4 introduced a new material to Sonus faber's loudspeaker production.
The front baffle and cork structure are covered in a plant-derived leather alternative produced by Italian company Ohoskin.
Made From Sicilian Agricultural By-Products
The material uses derivatives from Sicilian oranges and prickly pears.
Sonus faber describes it as one of its first non-fossil alternatives to conventional leather for this type of application.
Why Use It on the Baffle?
The baffle is one of the speaker's most visually prominent surfaces.
Covering it also continues the textural contrast between wood, leather-like material and metal that has long been part of Sonus faber's visual language.
Rear Reflex Duct
Concertino G4 uses a rear-mounted bass-reflex duct.
Sonus faber moved the port to the back of the cabinet compared with the preceding Concertino design.
Why Move the Port?
Sonus faber says the rear position helps avoid turbulence at the front of the loudspeaker.
It also makes room placement particularly important because the port interacts with the wall behind the cabinet.
Rear-Ported Does Not Mean It Must Be Far Into the Room
There is no universal distance that applies to every room.
The important point is that wall proximity changes the way bass behaves.
Start with some useful space behind the cabinet and experiment before deciding on the final position.
If the Bass Sounds Too Heavy
Move the speakers further from the rear wall and corners.
Nearby boundaries reinforce low frequencies, and excessive reinforcement can reduce bass definition.
If the Bass Sounds Too Light
Moving the speakers slightly closer to the rear wall can add some useful reinforcement.
Make small changes rather than moving directly from one extreme to another.
Avoid Tight Corner Placement
Placing a rear-ported speaker close to both a side and rear wall can increase bass considerably.
Where possible, give Concertino enough room to establish a more balanced relationship with the surrounding boundaries.
60Hz–25kHz Frequency Response
Sonus faber specifies the Concertino from 60Hz to 25,000Hz.
That immediately tells us something useful about how the speaker should be approached.
It Is Still a Compact Standmount
Concertino is not designed to imitate the low-frequency scale of a large floorstander.
Its priorities are compact proportions, controlled bass and the integration of its midwoofer and tweeter.
Does 60Hz Mean There Is Nothing Below 60Hz?
No.
A published frequency-response limit does not represent a brick-wall cutoff. Output normally rolls away progressively below the specified range.
Will It Reproduce Bass Guitar?
Yes, although the lowest fundamental information will naturally have less acoustic output than it would through a much larger loudspeaker or properly integrated subwoofer.
Does Concertino Need a Subwoofer?
Not automatically.
For acoustic music, vocals, jazz, chamber music and ordinary listening levels in an appropriate room, many listeners may prefer the simplicity of the stereo pair by itself.
A subwoofer becomes more useful if:
- You listen to electronic music with substantial sub-bass
- You want the lowest octave of pipe organ
- You want greater scale from rock and large orchestral recordings
- You are building a home cinema system
- You want more bass headroom at higher playback levels
Don't Add a Subwoofer Before Positioning the Concertino Properly
Room position can change the perceived bass balance substantially. Optimise the speakers first, then decide whether additional low-frequency extension is genuinely required.
85dB Sensitivity
Concertino is specified at 85dB sensitivity.
That is lower than many larger passive loudspeakers, so it benefits from an amplifier with sensible power and current delivery.
4O Nominal Impedance
Sonus faber specifies the nominal impedance at 4O.
This means amplifier choice deserves more consideration than simply assuming any small integrated amplifier will be suitable because the speaker itself is compact.
30–150W Recommended Amplifier Power
The official recommendation runs from 30 watts to 150 watts per channel.
That is a broad range, but room size and listening level determine how much power is useful in practice.
Will a 30W Amplifier Work?
Yes, because 30W sits within Sonus faber's recommendation.
It is best suited to sensible listening levels, shorter listening distances and an amplifier that remains comfortable into a 4O load.
Would 50W Be Enough?
A capable 50W amplifier can be an excellent starting point in a small or medium-sized room.
The quality of the power supply and 4O performance matter as much as the headline wattage.
What About 80–100W?
This provides useful additional dynamic headroom and is a very sensible region for a high-quality integrated amplifier partnered with Concertino.
Can I Use 150W?
Yes. That sits at the top of Sonus faber's published recommendation.
A 150W amplifier does not continuously feed 150 watts into the speaker. It simply has greater output capability available for musical peaks.
Why Current Delivery Matters
A 4O speaker draws more current from an amplifier than a nominal 8O load at the same voltage.
A well-designed amplifier should therefore remain stable and controlled into lower impedances rather than merely quoting an attractive power figure into 8O.
Don't Underestimate These Because They're Small
Concertino G4 is compact, but 85dB sensitivity and 4O impedance mean it deserves a serious amplifier. A good demonstration with your intended electronics is much more useful than choosing amplification by wattage alone.
Valve Amplifiers
Concertino can potentially be used with suitable valve amplification, but its 85dB sensitivity and 4O nominal load mean very low-powered designs require careful consideration.
If using a valve amplifier with selectable output-transformer taps, follow the amplifier manufacturer's recommendations and audition the combination where possible.
Solid-State Amplifiers
A capable solid-state integrated amplifier or pre/power combination is a natural partner.
Look for good performance into 4O and sufficient headroom for your room and preferred listening level.
Class D Amplifiers
A well-designed Class D amplifier can also be entirely suitable provided it is comfortable with the 4O load.
Streaming Amplifiers
Concertino's compact form makes it particularly attractive with premium all-in-one streaming amplifiers.
The speaker provides the craftsmanship and physical presence, while the electronics can remain relatively discreet.
Good for Vinyl?
Yes.
Its focus on two-way simplicity, natural-fibre driver material and stereo imaging makes Concertino an interesting partner for high-quality turntables.
Audio T has also demonstrated Sonus faber speakers successfully in Rega-based vinyl systems.
Good for Streaming?
Absolutely.
There is nothing inherently analogue about Concertino. A quality network streamer and amplifier can exploit the speaker just as effectively as a turntable or CD player.
Good for CD?
Yes. A capable CD player or transport and DAC feeding suitable amplification makes a perfectly natural system.
Good for Vocals?
This is an area where a well-integrated compact two-way speaker can be particularly convincing.
The midwoofer covers the majority of the vocal range before meeting the tweeter at 1700Hz, so crossover integration is central to how voices are presented.
Good for Jazz?
Yes, particularly smaller-scale recordings where stereo placement, tonal colour and midrange detail matter more than extreme low-frequency output.
Good for Acoustic Music?
Concertino is naturally suited to acoustic instruments, vocals and smaller ensembles where timbre, stereo imaging and low-level detail are priorities.
Good for Classical Music?
Yes, particularly chamber music and smaller ensembles.
Large orchestral recordings can also sound excellent, although a larger loudspeaker or subwoofer can provide greater low-frequency scale in a bigger room.
Good for Rock?
Yes, but room size and expected listening level matter.
If large-scale bass weight is a priority, a larger Sonus faber model may be the more natural choice.
Good for Electronic Music?
The speaker can reproduce electronic music very well through the midrange and treble, but its 60Hz published lower limit means listeners focused heavily on deep synthesised bass may want to consider a subwoofer.
What Size Room Suits Concertino G4?
Small and medium-sized listening spaces are its natural environment.
The compact cabinet is easy to accommodate visually, although the rear reflex duct still benefits from sensible space around the speaker.
Can It Work in a Large Room?
Yes at sensible levels and listening distances, but the combination of 85dB sensitivity and compact bass system means larger Sonus faber loudspeakers offer more effortless room-filling scale.
Dedicated Iron Stands
Sonus faber created the Iron Stand specifically for Concertino G4.
It combines an industrial iron structure with walnut veneer detailing and forms a striking contrast with the compact wooden cabinet above.
What Are the Iron Stands Made From?
Sonus faber specifies iron and walnut veneer.
The main structure is formed from an IPE 120 x 64 beam, deliberately giving the stand an architectural, industrial appearance.
Iron Stand Dimensions
- Height: 730mm
- Width: 270mm
- Depth: 320mm
- Weight: 14.5kg each
Overall Height With the Iron Stand
Sonus faber publishes a complete speaker-and-stand height of 1044mm.
The total footprint becomes 270mm wide and 320mm deep.
Why a Heavy Stand?
The Iron Stand itself weighs considerably more than the 6.6kg speaker cabinet.
That mass and structural rigidity create a firm mechanical foundation while placing the speaker at the intended listening height.
Can I Use a Different Stand?
Yes.
The Concertino itself is sold separately from the Iron Stand, so another suitably stable support can be used.
Look for:
- Appropriate height
- A suitably sized top plate
- Good lateral stability
- Enough load capacity for a 6.6kg speaker
- Freedom to position the loudspeaker away from the rear wall
Can Concertino Go on Furniture?
It can, provided the support is stable and gives the speaker enough room to operate properly.
A dedicated stand normally gives far greater control over placement and listening height.
Can It Go on a Bookshelf?
Physically yes, but the rear reflex duct makes a tightly enclosed shelf less than ideal.
Concertino is better treated as a true standmount loudspeaker despite Sonus faber's use of the broader "bookshelf" classification.
Speaker Dimensions
- Height: 314mm
- Width: 214mm
- Depth: 297mm
- Weight: 6.6kg per speaker
Compact Without Feeling Conventional
At just over 31cm high, Concertino occupies relatively little visual space.
The unusual trapezoidal cabinet and combination of walnut, cork and leather-like material nevertheless give it far more visual character than a conventional rectangular standmount.
One Finish, Deliberately Chosen
Concertino G4 is presented in Sonus faber's characteristic combination of solid walnut, black plant-based leather and brass.
Rather than offering a large range of colours, the materials themselves form part of the identity of the speaker.
Concertino G4 vs Concertino Maestro
The Concertino Maestro is a separate limited edition created to mark the thirtieth anniversary of the original Concertino.
Only 300 pairs were produced, each distinguished by an individually numbered brass plaque inset into the walnut side panel.
The standard Concertino G4 on this page is the regular current production model, not the limited Maestro edition.
This Is Not the Maestro Limited Edition
The Concertino Maestro is a separate 300-pair anniversary edition. This Audio T listing is for the standard current Concertino G4 unless specifically stated otherwise.
Concertino G4 and the Heritage Collection
Concertino sits within Sonus faber's Heritage Collection alongside larger designs that explore similar themes of solid wood, traditional proportions and modern acoustic engineering.
For customers attracted to the design language but needing more bass extension or scale, moving further up the Heritage range is worth considering.
Concertino or a Larger Sonus faber?
Choose Concertino when:
- Your room is small or medium sized
- You want a compact speaker
- You value solid wood and handcrafted construction
- You prefer a simple two-way system
- You can provide a capable amplifier
- Extreme bass extension is not the first priority
Consider a larger model when:
- Your room is large
- You listen from a greater distance
- You regularly listen at high levels
- You want substantially deeper bass without a subwoofer
- You want greater dynamic scale
Speaker Positioning
Good positioning can transform a pair of compact standmount speakers.
Begin with the pair symmetrically placed where practical and allow some space around the rear reflex ports.
Speaker Spacing
The ideal distance between the speakers depends on the listening distance and room.
A centrally recorded voice should appear convincingly between the cabinets rather than leaving a weak or disconnected middle to the soundstage.
Toe-In
Start with a modest inward angle and adjust in small steps.
Listen for the balance between:
- Central image focus
- Soundstage width
- Depth
- Treble balance
- Consistency across the listening area
Don't Optimise While Standing Up
Make positioning decisions from the normal seated listening position.
The height and angle of the speaker relative to your ears affect the tonal balance and stereo image.
Recommended Concertino G4 Setup Routine
- Unpack both speakers carefully and retain all packaging.
- Inspect the solid walnut and other cabinet surfaces before installation.
- Position the speakers on suitable rigid stands.
- Use the dedicated Sonus faber Iron Stands where appropriate.
- Ensure both stands are level and stable.
- Begin with useful space behind the rear reflex ports.
- Avoid placing either speaker tightly into a corner.
- Position the stereo pair broadly symmetrically.
- Start with a modest amount of toe-in.
- Switch the amplifier off before connecting speaker cable.
- Check positive and negative polarity on both channels.
- Begin playback at a moderate level.
- Use a familiar vocal recording to judge centre-image focus.
- Adjust toe-in in small increments.
- Play familiar music with acoustic bass or kick drum.
- If bass is excessive, move the speakers further from the rear wall.
- If bass is too light, experiment with slightly greater wall reinforcement.
- Listen to several different musical styles.
- Only judge amplifier or cable changes after the speaker position is properly established.
Caring for Solid Walnut
The cabinet uses real natural materials and should be treated accordingly.
Avoid aggressive household cleaning products, excessive moisture and abrasive cloths.
Use a clean, soft cloth and follow Sonus faber's current care instructions supplied with the loudspeakers.
Natural Variation Is Part of the Design
Real wood is not perfectly uniform.
Variations in grain and tone are part of the character of a solid walnut loudspeaker rather than defects in a printed finish.
Registering the Speakers
Sonus faber currently invites owners to register their product within 30 days of purchase to obtain its available extended-warranty coverage under the manufacturer's current terms.

Can Concertino sit on furniture?
Yes where the furniture is suitably stable, although separate stands generally provide much greater positioning freedom.
Can Concertino go inside a bookshelf?
It can physically fit in some shelving, but the rear reflex duct means a tightly enclosed shelf is not the preferred acoustic starting point.
Is Concertino rear ported?
Yes. Concertino G4 uses a rear-mounted reflex duct.
Why did Sonus faber move the port to the rear?
The manufacturer says the change helps avoid turbulence at the front of the loudspeaker.
Does a rear port mean the speaker cannot go near a wall?
No, but wall distance affects bass balance. Experiment rather than assuming one fixed distance.
What should I do if the bass sounds boomy?
Try moving the speakers further from the rear wall and corners.
What if the bass sounds too light?
Experiment with slightly greater rear-wall reinforcement.
Is Concertino a two-way speaker?
Yes.
What drivers does it use?
A 1.1-inch D.A.D. Arrow Point tweeter and one 5.25-inch ferrite-magnet midwoofer.
What does D.A.D. stand for?
Damped Apex Dome.
What does the D.A.D. tweeter do?
It damps the apex of the soft dome to control unwanted anti-phase behaviour at high frequencies.
Is the tweeter silk?
Yes. Sonus faber describes it as a soft silk dome.
How large is the tweeter?
The official technical specification states 1.1 inches.
How large is the midwoofer?
5.25 inches.
What is the midwoofer cone made from?
Paper pulp.
What type of magnet does the midwoofer use?
Ferrite.
What is the crossover frequency?

It can provide additional extension below the Concertino's natural low-frequency range, particularly with recordings containing deep synthesised bass.
What is the sensitivity?
85dB.
What is the impedance?
4O nominal.
Is Concertino difficult to drive?
It is not exceptionally difficult, but 85dB sensitivity and a 4O nominal impedance mean it deserves a capable amplifier.
What amplifier power does Sonus faber recommend?
30 to 150 watts per channel.
Will a 30W amplifier work?
Yes, provided it is comfortable with a 4O speaker and suits the room and required listening levels.
Can I use a 50W amplifier?
Yes. A capable 50W amplifier can be a very sensible match.
Can I use a 100W amplifier?
Yes.
Can I use a 150W amplifier?
Yes. Sonus faber lists 150W as the upper end of its recommendation.
Can I use a valve amplifier?
Potentially, but very low-powered valve designs should be considered carefully because Concertino combines 85dB sensitivity with a 4O nominal load.
Can I use Class D amplification?
Yes, provided the amplifier is comfortable driving 4O speakers.
Can I use a streaming amplifier?
Yes. A high-quality streaming amplifier can make an excellent compact system with Concertino.
How big is each Concertino?

How much does each speaker weigh?
6.6kg.
What is the cabinet made from?
Sonus faber specifies solid wood, cork and plant-based leather among the primary cabinet materials.
What wood is used?
Solid walnut.
Why is the walnut ribbed?
Sonus faber says the ribbing adds structure and rigidity to the cabinet and reduces the need for conventional internal bracing.
Why does Concertino use cork?
The cork central chassis is designed to reduce internal resonance and decrease the quantity of additional damping material required.
Is the cork just decorative?
No. It is part of the acoustic enclosure design.
What is the leather made from?
Concertino uses a plant-based leather alternative produced by Ohoskin.
What is Ohoskin made from?
Sonus faber says it is sustainably sourced from derivatives of Sicilian oranges and prickly pears.
Is the Concertino cabinet real wood?
Yes. Sonus faber specifies solid walnut side walls.
What finish is available?

Why Buy Sonus faber Concertino G4 From Audio T?
Concertino G4 is exactly the sort of speaker where a specification sheet only tells half the story. Its 85dB sensitivity, 4O impedance and compact dimensions are useful information, but the real decision comes down to how its two-way driver system, solid-walnut enclosure and unusual cork architecture work with your amplifier and room.
Audio T can help with amplifier matching, positioning, stand choice and complete system planning. We can also demonstrate how a compact Sonus faber behaves with vinyl, CD and streaming sources and help decide whether the dedicated Iron Stands or another support solution makes most sense in your room.
