What reviewers think
Bloggers and YouTubers have tried this product—so we've summarized their strongest opinions below. Links to full reviews follow.
Product Strengths
- The Rubicon 6C speakers establish a large, easy-to-follow soundstage and lay it out unequivocally, even when playing a slightly murky mix
- The Rubicon 6C demonstrates wonderful rhythmic prowess and engages the listener physically, emotionally, and intellectually
- The Rubicon 6C offers good dynamic headroom for its size and retains its poise and full frequency range even at modest volumes
- The cabinet is built and finished with unarguable expertise
- There is an immediate and obvious amount of bass punch, depth, and force of the bass response
Product Considerations
- The Rubicon 6C requires a little breathing space and needs to be about 30cm from both rear and side walls
- The Sound Hub is far from the most luxurious-looking or -feeling product
- Some reviewers found the bass to be too prominent in their listening environment
- The DSP performs some dynamic limiting at very loud volumes, to prevent amplifier clipping, but unlike DSP-based active speakers from companies such as Dynaudio and KEF, the active Rubicons lack room-boundary compensation
Takeaway: The Rubicon 6C is a convenient, low-cable way to establish an audio system that is adaptable in terms of sound and functionality and capable of delivering audiophile-quality playback. This system makes it easy to enjoy high-resolution music without the long-term stress of configuring a complex setup.

Our take on the brand
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.
Product Strengths
- Gorgeous sound is clear, smooth, detailed, and dynamic
- Elegant design is dashingly elegant, minimalist aesthetic, and painstakingly crafted for equal parts style and substance
- Impressive bass extension and output, described as deep and firm, surprising for their size
- Clear midrange makes voices sound purposeful, characterful, and entirely present
- Versatile connectivity with streaming and input options, including Chromecast, AirPlay 2, phono pre-amp, and HDMI ARC/eARC
Product Considerations
- Some reviewers experienced streaming and HDMI ARC reliability issues
- Input and control layout can be inconvenient and awkward
- Prototype unit had operational bugs
- No bass level adjustment is available, though it could be added in mobile app
Comparisons (according to reviewers)
- Vs KEF LS50 Wireless II—the KEF LS50 Wireless II is a similarly high-end option
- Vs PSB Alpha iQ—the PSB Alpha iQ is a more compact wireless speaker package than the Sonus Faber and is comparatively lighter on bass
Takeaway: The Sonus Faber Duetto speakers are well-suited for those seeking amazing sound and a beautiful design in one package. These speakers are easy to connect and use, and fill the room with rich, detailed audio.

Our take on the brand
Our Summary
Product Strengths
- The Kin Play Tower 2s are active speakers, meaning they have a built-in amplifier, offering a cleaner and simpler setup compared to passive speakers that require an external amplifier
- The speakers are reported to have a frequency response range down to 30Hz, meaning that a subwoofer may not be necessary for many listeners
- Available in black and white satin finishes, the speakers are compact enough to fit in various listening spaces, combining good looks with good sound
- Multiple inputs including HDMI ARC, optical inputs, Bluetooth, stereo RCA, line-level, and active phono inputs offer versatile connectivity options
Product Considerations
- Modern connectivity options fall a little short, opting for HDMI ARC instead of eARC, and lacking WIFI and/or Ethernet
- Bypassing the internal preamp using the 'amp in' input can cause the speakers to play at full volume, potentially damaging the speakers or hearing if the connected device has a fixed volume output
- At higher volumes, the five-inch drivers can struggle with demanding bass sections, so the speakers may benefit from the support of a subwoofer when playing bass-heavy music
Comparisons (according to reviewers)
- Kin Play Tower 2s have a bass that is punchy and dynamic, while Martin Logan Towers tend to have deeper sounding bass
- Bowers & Wilkins speakers are brighter
Takeaway: The Kin Play Tower 2s are convenient and versatile active speakers that sound great and are easy to set up. They offer a clean aesthetic and multiple connectivity options, making them suitable for those seeking quality audio without a complex setup.

Our take on the brand
Our Summary
Product Strengths
- Sound is hifi and they can play bass
- Significantly more bass capacity than the A4, suitable for larger living rooms
- Midrange reproduction is very nice, and singing voices sound natural
- Treble is well-resolved, and gives a bright and delicious sound image
- Practical and good, it makes economic and technical sense to have everything together on one plate, where all the inputs and outputs are located
Product Considerations
- The sound can be a bit sharp, and the nuance could have been better
- The active electronics are located in the left speaker, which must be in the left corner of the living room
- Handling the large and 26 kilo heavy cardboard box is a task for two people
Comparisons (according to reviewers)
- Vs Forte A4: the Forte A55 keeps up the quality, but has significantly more capacity when it comes to the bass
Takeaway: The Argon Audio Forte A55 is a great value speaker with the same good sound that was characteristic of little brother Forte A4, only for larger living rooms and with the possibility of deeper bass and higher sound pressure. Being a truly active speaker in its price range makes it worth buying.
