Mu-so Qb is a wireless music system alive with innovation.

Every component tailored

One of the biggest design challenges with Mu-so Qb was to configure the individual speakers within the smaller cabinet. To achieve that distinctive Naim sound, our engineers had to interrogate every component and adjust speaker angles by the smallest of fractions. It led us to an arrangement of five drivers, offset and angled perfectly to create a left-right dispersion asymmetry. In this arrangement are two microfibre dome tweeters and two mid drivers, all driven by 50W amplifiers. For low frequencies we’ve installed two pistonic passive bass radiators. These work alongside a custom-made woofer that’s driven by a 100W amplifier to create an astonishing bass sound for a system this size. 

Controlling the Mu-so Qb sound

At the heart of Mu-so Qb is a 32-bit digital signal processor - the same high-spec component used in the original Mu-so. Fine-tuned in our listening room, it controls the flow of music information to each speaker. The DSP also includes two EQ settings, tailoring the best sound quality whether close to or away from the edge of any room. The end result is a refined audio experience with no distortion, increased speaker accuracy and an expansive sound that makes hairs stand on end.

Mu-so Qb has two passive radiators. They work in conjunction with a custom-made woofer that’s driven by a 100W amplifier to create astonishing low frequencies.
The whole cabinet sits on an illuminated base of high-grade acrylic that provides the foundation for the electronics and speakers to shine.
Our audio engineers installed microfibre dome tweeters for their stiffness and dampening qualities.
Custom mid-range drivers provide crystal clear speech and emotively powerful vocals. They’re also carefully positioned to evenly disperse sound.
Driving Mu-so Qb is a 32-bit digital signal processor. It’s the same high-spec design as in the original Mu-so system, but it has been finely tuned by our engineers to work perfectly with the smaller cabinet space. It controls the flow of music information to each individual speaker and draws on all our experience designing the best in-car audio systems for Bentley motors.
At the core is the volume control – made from a solid aluminium ring – which runs the circumference of the touch screen interface with its patent-pending illumination system.
The main body is made from a 20% glass-filled polymer, chosen for its strength, rigidity and dampening.
At the back of the unit an extruded aluminium heat sink has been installed to maximise thermal performance.

Rated 5 out of 5 by from Rich powerful and detailed sound Bought this unit for our kitchen, as we were so impressed with our Uniti unit. Great set of features with the iRadio, access to my music on the network & streaming services, all via a wireless connection, and controllable from my phone. So there's not much missing in terms of features. Sounds quality is excellent, plenty of detail, a lovely rich almost analogue tone and rhythm. The little QB goes plenty loud enough for me, and on top of all that, it looks great! OK so there are cheaper alternatives, but there's really nothing else for the same money that looks, sounds and works as well in my book. Still loving my QB after almost a year.

Rated 5 out of 5 by from Compact Big Sound I owned an original Naim Nait amplifier many moons ago so know the quality of their products. Fast forward to the present day digital world; the Mu-so Qb has all the attributes of a high end sound system with the added benefit of a small footprint. Easy to set up with Naim's excellent technical support on hand if needed. It has a host of of streaming features over Wi-Fi or Bluetooth, plus wired connections. On the rear are 3.5mm and optical inputs, as well as a USB socket to let you play files from a USB drive, or from an iOS device. Oh yes, the design is gorgeous; from the flywheel motion control dial, the curves and the glowing base!

Rated 5 out of 5 by from Amazing Sound I originally bought a Bose but was so disappointed with the sound quality I returned it in a matter of days. On recommendation of the sales associate, I looked at Naim, having never heard of the brand before. Even though it was more than I planned to spend I knew I wasn’t going to get anything of superior quality without paying for it and saw it as a long term investment without the need to upgrade in a few years. I brought the speaker home and the sound quality was astounding, clear and crisp. Unfortunately mp3’s and digitally produced music etc dont always give you the same quality of sound compared to pre digitally produced tracks.

Rated 4 out of 5 by from Great Sound Quality & Looks Having been used to a competitor’s product I discovered the QB at Bristol Hifi show. The sound emanating from the tiny cube was impressive even with all the noise from the enthusiasts & adjacent stands. A subsequent listen in a “friendlier” environment convinced me that my existing streaming equipment had to go. I have been using my QB for around 18 months and the clarity & big sound still impresses me and unsuspecting friends. My only gripe is that the device is not “Roon Ready” although Apple AirPlay does work well but doesn’t do the QB justice. On sound quality alone this machine deserves 5 stars but I want that Roon compatibility so -1 Star.
