Audio T Verdict
The ProAc Response DB3 offers much of the natural balance, strong imaging and room-filling character associated with the Response range from a compact and comparatively accessible standmount speaker.
Its 127mm long-throw Pagina Mica bass and midrange driver produces surprisingly rich and extended bass, while the transparent dust cap and carefully developed crossover help maintain a smooth transition through the vocal range.
ProAc’s 25mm silk-dome tweeter provides a sweet, detailed and refined top end that remains easy to enjoy across long listening sessions.
The rear-facing reflex port means positioning deserves care, but mounted on suitable stands and partnered with a capable amplifier, the DB3 can create a spacious soundstage that appears considerably larger than the cabinets.
Its 88.5dB sensitivity and 8-ohm nominal impedance make it slightly more amplifier-friendly than the Response DB1D, while the DB1D remains the choice for those seeking greater bass extension and a more advanced main driver.
ProAc Response DB3 Standmount Speakers
The ProAc Response DB3 is a compact two-way standmount loudspeaker designed to bring the company’s natural tonal balance and spacious presentation to a more accessible point within the Response range.
It combines a 127mm long-throw Pagina Mica bass and midrange driver, transparent dust cap, 25mm silk-dome tweeter and a dedicated crossover within a compact rear-ported cabinet.
A quoted frequency response of 38Hz to 30kHz gives the DB3 impressive bass extension for a speaker measuring only 320mm high.
Amplification and Speaker Stands Are Required
The Response DB3 is a passive loudspeaker and does not contain amplification, streaming, wireless connectivity or volume control.
A suitable stereo amplifier, speaker cables and a stable pair of speaker stands will be required.
A More Accessible Response Standmount
The DB3 has similar external dimensions to the Response DB1D but uses a different cabinet structure, bass driver and crossover.
These changes allow ProAc to offer a compact Response-series loudspeaker at a lower price while retaining the natural midrange, sweet treble and expansive soundstage associated with the range.
Its slightly higher sensitivity also makes the DB3 a little easier to drive than the DB1D on paper.
Compact Does Not Mean Background Listening
The DB3 may have a relatively discreet cabinet, but it is designed as a serious two-channel loudspeaker rather than a small lifestyle or desktop speaker.
It will reward suitable stands, careful positioning and good-quality source equipment and amplification.
127mm Long-Throw Bass and Midrange Driver
The Response DB3 uses a 127mm ProAc bass and midrange driver with a long-throw design.
The driver’s extended travel allows it to move a greater volume of air than a more restricted small driver, helping the compact speaker reproduce deeper bass and stronger musical dynamics.
A raised spider and linear motor system help maintain controlled movement as the cone travels forwards and backwards.
Pagina Mica Cone
The bass and midrange driver uses ProAc’s Pagina Mica cone material.
The material is selected to combine the rigidity required for clean bass reproduction with the controlled behaviour needed through the midrange.
This helps the DB3 deliver a rich and substantial presentation without obscuring voices, guitars and other instruments occupying the centre of the musical range.
Updated Cone Description
Older product information sometimes describes the DB3 cone as “mikapulp”.
ProAc’s current product page and catalogue identify the material as Pagina Mica.
Transparent Dust Cap
A transparent dust cap covers the centre of the bass and midrange driver.
Its design allows information generated around the voice-coil area to contribute to the upper response of the driver.
This helps create a smoother transition between the main driver and the silk-dome tweeter.
Special Driver Surround
The DB3 bass and midrange unit uses a specially developed surround matched to its long-throw movement.
The surround helps control the cone across both small and larger excursions, maintaining consistency as listening levels increase.
It works alongside the raised spider and linear motor system as part of the complete driver assembly.
25mm Silk-Dome Tweeter
The Response DB3 uses ProAc’s 25mm silk-dome tweeter with a special cooling fluid.
ProAc selected the tweeter for its flat response, fine detail and naturally sweet tonal character.
The same basic tweeter approach is used across several ProAc models, helping the DB3 retain the familiar and musically balanced presentation of the Response range.
Smooth High-Frequency Presentation
The soft-dome diaphragm is designed to reproduce high-frequency information without making the speaker sound unnecessarily hard or aggressive.
Cymbals, strings, vocal harmonics and room ambience remain clearly audible, but are integrated into the music rather than pushed artificially forward.
The final treble balance will still depend on the amplifier, source equipment, room furnishings and speaker positioning.
38Hz Bass Extension
ProAc specifies a frequency response extending from 38Hz to 30kHz.
This gives the DB3 convincing weight with bass guitar, drums, piano and orchestral recordings despite its compact cabinet.
The bass achieved within a particular system will depend on the room, speaker stands, amplifier and distance from nearby walls.
Does the DB3 Need a Subwoofer?
Not necessarily. Its quoted 38Hz extension should provide sufficient bass for many music systems in small and medium-sized rooms.
A carefully integrated subwoofer can still add the lowest octave and greater physical scale where required.
Rear-Facing Reflex Port
A single reflex port on the rear of the cabinet reinforces the DB3’s low-frequency output.
The port works with the cabinet volume and long-throw driver to achieve bass extension that would be difficult from a similarly sized sealed enclosure.
Its distance from the rear wall will have a noticeable effect on bass quantity and definition.
Allow Space Behind the Speakers
Positioning the DB3 very close to a rear wall or corner may increase bass output but reduce clarity and control.
Begin with some space behind each speaker and make small adjustments while listening to familiar music.
Dedicated Crossover
The crossover has been developed specifically for the DB3’s long-throw bass driver and silk-dome tweeter.
Selected components are mounted on a dedicated circuit board to divide the incoming signal between the two drive units.
The design aims to create a seamless transition through the crossover region so that voices and instruments remain coherent.
Oxygen-Free Copper Internal Cable
Multistrand oxygen-free copper cable is used for the internal wiring.
The cable connects the rear input terminals, crossover and drive units within each cabinet.
This forms part of ProAc’s complete loudspeaker design rather than relying on the drive units alone to determine performance.
Bi-Wiring and Bi-Amplification
The crossover is split to support optional bi-wiring and bi-amplification.
For conventional single-wire operation, the high-frequency and low-frequency terminals must remain connected using the fitted terminal links.
Bi-amplification should only be attempted using suitable equipment and a clear understanding of the amplifier and loudspeaker connections.
Check the Terminal Links
For normal single-wire use, both crossover sections must remain joined by the correctly fitted terminal links.
When bi-wiring or bi-amplifying, switch off the amplifier and remove the links before connecting separate cables or amplifier channels.
88.5dB Sensitivity
The Response DB3 has a quoted sensitivity of 88.5dB for one watt measured at one metre.
This is reasonably efficient for a compact high-performance standmount speaker and gives the DB3 a one-decibel advantage over the Response DB1D.
The amplifier should still provide sufficient clean power for the listening distance, room size and preferred volume.
8-Ohm Nominal Impedance
The nominal impedance is specified at 8 ohms.
This makes the DB3 a comparatively accommodating electrical load for a compact high-performance speaker.
Nominal impedance alone does not determine amplifier suitability, so sensitivity, room size and required playback level must also be considered.
20W to 100W Recommended Amplification
ProAc recommends amplifiers rated between 20W and 100W per channel.
A carefully chosen lower-powered amplifier may work well in a compact room at moderate volume, while larger rooms and higher listening levels will require greater clean output.
Power-supply quality, control and distortion performance are more important than simply choosing the largest available wattage figure.
Underpowered Amplifiers Can Also Cause Damage
An amplifier driven beyond its clean operating range may clip and produce high levels of distortion.
Choose an amplifier with appropriate headroom for the room, listening distance and required playback level.
Matching the DB3 with an Amplifier
The DB3 can be used with a broad range of suitable solid-state and valve amplifiers.
A good partner should preserve the smooth treble and natural midrange while maintaining firm control over the speaker’s extended bass.
Where possible, audition suitable amplifiers with familiar recordings rather than relying solely on specifications.
Stand Mounting
ProAc specifies the Response DB3 for stand mounting.
A rigid and stable stand should support the cabinet securely, resist unwanted movement and position the tweeter close to seated ear height.
The stand should also have a top plate of an appropriate size for the DB3’s 182mm-wide and 280mm-deep cabinet.
Each Speaker Weighs 8.8kg
The chosen stands must be stable and capable of safely supporting the speakers.
Additional care should be taken in homes with children or pets.
Positioning the ProAc Response DB3
- Use rigid and stable speaker stands
- Position the tweeters close to seated ear height
- Begin with some space behind the rear-facing reflex ports
- Keep both speakers the same distance from the listening position
- Avoid placing one speaker significantly closer to a corner
- Keep the rear ports unobstructed
- Adjust toe-in to balance focus and soundstage width
- Make small changes and listen between adjustments
Toe-In and Stereo Imaging
A small amount of toe-in towards the main listening position provides a sensible starting point.
Increasing toe-in may sharpen centre-image focus and the placement of voices and instruments.
Reducing the angle can create a wider and slightly more relaxed soundstage, depending on the room and listening distance.
Natural Midrange
The main driver’s controlled cone, transparent dust cap and dedicated crossover help the DB3 reproduce voices and instruments with a natural tonal balance.
Its midrange remains open and detailed without being separated from the bass or treble.
This balanced character makes the DB3 suitable for a broad range of music rather than favouring one particular recording style.
Exceptional Soundstage for Its Size
Correctly positioned, the DB3 can produce a soundstage that appears substantially wider and deeper than the physical cabinets.
Voices and instruments can be located independently within the room rather than remaining attached to the speakers.
Equal listening distances, broadly symmetrical placement and careful toe-in are important if this performance is to be fully realised.
Compact Cabinet
Each cabinet measures approximately 320mm high, 182mm wide and 280mm deep.
The narrow front baffle keeps visual impact relatively low and helps the speaker produce a focused stereo image.
Its 280mm depth must still be considered when selecting stands and allowing sufficient space behind the rear-facing reflex port.
Handcrafted in England
ProAc loudspeakers are handcrafted and tested at the company’s factory in Brackley, England.
The cabinets, drivers, crossovers, internal wiring and finishes are brought together as parts of the same complete loudspeaker design.
Each pair is checked before leaving the factory.
Acoustically Transparent Grilles
The Response DB3 is supplied with acoustically transparent crimplene grilles.
Magnetic grilles are available with certain cabinet finishes.
The precise grille arrangement should be confirmed for the chosen finish when ordering.
Standard Cabinet Finishes
The Response DB3 is available in Black Ash, Cherry, Walnut, Natural Oak and Silk White as standard finishes.
The real-wood veneers are selected and matched to provide a consistent appearance across each stereo pair.
Natural variations in grain and colour should be expected because genuine wood veneer is used.
