Powerful, rich sound in a compact design. Designed for both digital and analog sources, Duetto is a versatile combination of Italian style and contemporary function. Big sound in a compact design, Duetto marks Sonus faber's inaugural active stereo wireless speaker system. Powered by four bespoke amplifiers, Duetto presents an all-in-one sound solution, harmoniously blending a multitude of connectivity options while keeping the listening experience wire-free.
Double the sound, not the size. Inspired by a harmony produced by two instruments, Duetto sets a new standard for wireless high-fidelity sound in a compact design.
Ultra Wide Band Technology
Duetto employs Ultra Wide Band (UWB) technology, enabling communication between the two speakers. The wireless transmission avoids latency and interference by other home networks, while guaranteeing a wide frequency spectrum to send data signals at high speeds.
SENSO™ Technology by Sonus faber
The leather top panel allows the user to control and set up speaker functions — such as playback, volume, input selection, and connections — with a buttonless interface through simple fingertip gestures.
Sonus faber's iconic lute-shaped design takes inspiration from musical instruments. Crafted from wood, the cabinet ensures structural solidity, rich timbre, and musicality, while effectively eradicating internal resonances to shape the unmistakable Sonus faber Natural Sound.
Hear – and see – to believe. Duetto takes note of Sonus faber's most iconic design cues and natural materials.

Our take on the brand
Our summary
Product Strengths
- Remarkable sound power and early directivity indexes make it a true point source speaker.
- Special sound quality for the price offers a level of performance not typically found in speakers at this price point.
- Very good neutrality is present when the speaker is turned off axis.
- It is a very versatile speaker to drive.
- The midrange presentation is very dead center and coherent.
Product Considerations
- The bass does not reach as low as some listeners might prefer.
- The speaker can get bright at times.
- Care should be taken to place it not directly on axis, because when placed directly on axis, it is no longer a neutral speaker.
- There's no stand included in the package.
- It is made in China, and construction can be suspect.
Comparisons (according to reviewers)
- Vs PureAudioProject Duet 15, the SourcePoint 10 is more precise and focused, while the PureAudioProject has a bigger soundstage.
- Vs Fleetwood Deville SQ, they sounded more alike than different when in action, but SourcePoint was more extended from top to bottom and brought more lively dynamics and impact.
- Vs Klipsch Heresy IV, the SourcePoint 10 is the superior speaker in every way from build to sound, with more refinement and smoothness, and it seems just as dynamic as the Klipsch.
- Vs Dynaudio Special 40s, the SourcePoint 10 sounds much bigger, more dynamic, has much better bass, and fills a room with ease.
- Vs KEF LS50 META, the LS50 sounds smaller, leaner, and not as special in the vocal region.
Takeaway:
The SourcePoint is a speaker with a neutral sound that originates from a single point, and it has remarkable early directivity indexes. It is a speaker that offers very good performance for the money, but careful attention needs to be paid to its placement in the room.

Our take on the brand
I am the overperforming little guy who will demand your respect after your first audition. I can be a serious 2 channel system with a subwoofer, an LCR, or a surround channel. Effortless dynamics and lightspeed transients remain the common thread of all Signature series speakers including the S4b. A bookshelf with this much technology is hard to find and can literally be the Ninja of any system. Bookshelf, main for a 2.1 system, LCR, Dominus Surround, it can transform into anything you need.
Features including our proprietary DPC-Array controlling Mid/High frequencies and centered by our finest 28mm Beryllium dome and dual 28mm TPCD ultra-lightweight domes. All transducers are developed ground up by our engineers bringing decades of research and culminating in this world class design. All S-Series speakers share the same DPC-Array and benefit from our unique timbre matching technique across the entire series utilizing Beryllium and our advanced Carbon fiber.
These speakers are an acoustic suspension to meet the demands of any listening room with unparalleled dynamic range and musical finesse. Very impressive system alone or when combined with a PERLISTEN subwoofer. Great for use in 2.1 systems or any channel of theater system utilizing subwoofers. Can be used as surround, height or LCR. Bookshelf, stand or on-wall mounting with keyhole or available bracket.
Featuring our DPC-Array as for controlling Mid/High frequencies, centered by our finest 28mm Beryllium dome and dual 28mm TPCD ultra-lightweight domes. This new tweeter/waveguide DPC-Array delivers amazing accuracy, smoothness, and directivity control to handle the critical vocal range and delicate treble. The S4b shares the same DPC-Array and benefits from our unique timbre matching technique as found in the entire S-Series range of speakers. Unparalleled dynamic range, low distortion and musical finesse. The PERLISTEN S4b continues the lineup of speakers that have the distinguished honor to be the world's first and only loudspeakers to be certified for THX Dominus – their highest rating.
Product Strengths
- Solidly built with an inert cabinet, contributing to overall performance
- Crazy linear/neutral sound from about 100Hz upwards
- The beryllium tweeter provides nuanced, airy, and extended highs with a hint of shimmer for realistic metallic instruments
- It creates a three-dimensional soundstage, making the speakers disappear sonically
Product Considerations
- It does not have a great deal of bass on its own and may require a subwoofer for full-range playback, starting its roll-off at around 100Hz
- While placement is flexible, a solid amplifier is required
- The styling might be an acquired taste and could be considered overcomplicated by some
- The high gloss finishes may not appear different from less expensive speakers, making it harder to justify the luxury price tag
Comparisons (according to reviewers)
- Vs Bowers & Wilkins 805 D4: The S4B is more neutral/accurate, while the 805 D4 adds bass and treble energy
- Vs Focal Canta No. 1: The S4B outperforms the Canta No. 1, which has chestiness in its bass and midrange due to its cabinet
- Vs Revel Studio 2: The S4B reminded the reviewer of the Revel Studio 2, though the Revels had more bass
- Vs Focal Diablo Utopia: The Perlisten are a great alternative if the Utopias are outside of your reach and are a more neutral and less bright speaker
- Vs EgglestonWorks Nico Evo: The EgglestonWorks presentation is a little more mid-forward and less 3D than the Perlisten
Takeaway: The Perlisten S4b is a high-performing speaker that offers excellent clarity and a neutral sound, making it a great choice for audiophiles and home cinema enthusiasts alike. The speaker's ability to create a detailed and immersive soundstage can bring music and movies to life.

- Binding posts could be nicer
- Grills attract cats

Our take on the brand
Our Summary
Product Strengths
- Remarkably precise, unusually musical, and vivid sound, creating an open, inviting sound and bringing superb clarity and resolution to music
- Wide, airy, and holographic soundstage with excellent directivity, spreading reflections evenly for a consistent sound experience even when not in the 'sweet spot'
- Innovative Meta Material Absorption Technology (MAT) absorbs 99% of unwanted sound coming from the rear of the tweeter, leading to improved clarity, precision, and detail in the high frequencies—and better overall composure when the mix gets complicated
- A dedicated woofer handles the bass, allowing the coaxial system to focus on the important midrange without interference, which results in improved bass performance and power handling
- Neutrality and balanced frequency response, combined with excellent linearity, makes it very suitable for equalization, allowing users to adjust the sound to their preferences
Product Considerations
- The bass, while tight and tuneful, might not provide the 'gut punch' or chest-thumping experience some listeners prefer, and a subwoofer is recommended for those seeking more pronounced low-end dynamics
- The treble response, while detailed and airy, may sound a bit bright when the speaker is aimed directly at the listener (on-axis), and a slight toe-out (5-10 degrees) is recommended to relax the high frequencies
- Some reviewers note that they may sound a little flat or leaner at very low listening volumes, excelling more when given some 'juice' and volume
- The piano black finish, while beautiful, is prone to fingerprints and requires care to maintain its appearance
Comparisons (according to reviewers)
- Vs. LS50 Meta: Considered a better, more complete speaker with a more balanced presentation from top to bottom—and a more fleshed-out sound
- Vs. Bowers & Wilkins 705 S3: Puts the treble on a much tighter leash, while the 705 S3 can come on as just too much in that lower treble region
- Vs. Buchardt S400 Mark II: Is leaner, airier, and more spatial, while the Buchardt is warmer, thicker, and has more bass punch
- Vs. Revel M106: The Revel M106's directivity is nowhere near as good as the Kef R3 meta
Takeaway: The KEF R3 Meta is a well-rounded and high-performing loudspeaker, offering a detailed and balanced sound signature with excellent imaging capabilities. It is a great choice for those seeking a neutral and engaging listening experience.
Video review
Our take on the brand
Our Summary
Product Strengths
- Precise and stable stereo imaging
- Good detail retrieval
- Neutral tonal balance
- Versatile directivity
Product Considerations
- Bass extension requires a subwoofer for full-range playback, especially below the mid-40Hz range
- Potential for brightness, especially when toed-in directly towards the listening position
- Requires careful setup and experimentation with placement to optimize sound, especially in relation to the rear wall and toe-in
Comparisons (according to reviewers)
- The SourcePoint 8 is more neutral, with a less elevated top end, while the SourcePoint 10 is brighter
Takeaway: The SourcePoint 8 is a well-engineered speaker that stands out for its clear imaging and ability to convey musical detail across different genres. It offers a balanced and neutral sound that makes it an engaging listening experience.
