Naim Mu-so Qb Wireless Speaker System

Naim Mu-so Qb Wireless Speaker System

Key info

A more compact alternative to the Mu-so. Play music via Bluetooth AptX, AirPlay, UPnP Hi-Res Streaming, Spotify Connect or Tidal with Naim sound quality.

Naim Mu-So Qb is an award winning bluetooth speaker system and more compact version of the larger Naim Mu-So. The Mu-So Qb (pronounced “cube” owing to its cubic design) is a true feat of sound engineering. Easy control and simple connectivity, Mu-so Qb offers a remarkeable 300 watts to unleash your music with a sound defiant of its compact footprint.

Mu-so Qb shares the same DNA as the original award winning Naim Mu-so music system, all intuitively crafted into a compact and stylish cubic design. Like its larger brother, it too can be customised with optional coloured grilles.

Easy to use

Its advanced in design, yet very simple to use and its advanced connectivity will unleash your digital music, wherever it’s stored. Connect Mu-so Qb to a network via Ethernet or Wi-Fi to open up a world of music.

Choices comprise Spotify Connect, TIDAL, UPnP Airplay, Bluetooth/aptX, analogue and digital inputs, Internet radio, USB as well as Apple or Android App for full control. Virtually, everything you can request, all with the addition of Naim sound quality!

Multi Room Capability

Mu-so Qb can be combined with a second unit or with the full size Naim Mu-so system to stream music in various rooms, for the greatest multiroom experience. Pause and contemplate for a moment – this is the first offering from the flagship Naim brand for multi room audio! To say we’re excited about this is a huge understatement. Multi room Mu-So with all of the connectivity selections described above means you now have an excellent solution for an alternative multi room system. Just synchronise the units to perform the same song beat-for-beat in up to a choice of five rooms.

Components tailored for Qb

To achieve that unique Naim sound in such a compact enclosure, the engineers had to investigate every component and tweak speaker angles by the minutest of fractions. It resulted in an arrangement of five drivers, offset flawlessly to produce a left-right dispersion discrepancy.

Mu-so Qb uses a distinct configuration of seven bespoke speaker drivers – 1 x active bass, 2 x passive bass, 2 x mid-range and 2 x tweeters. Each is controlled individually by the DSP for complete accuracy. Tweeters and microfibre domes are of the greatest quality, while its mid drivers have rare earth magnets and copper capped poles for even more precision. And for low frequencies, Naim fitted two pistonic passive bass radiators that function beside a custom-made woofer.

Great Amplification

With each of the five drivers powered by separate balanced Class-D amps, there is 300W of total amplification able to deliver 50W to the mid-range and high-frequency drivers and 100W to the bass, to produce brilliant low frequencies for a system this small.

What also distinguishes the Mu-so Qb, is that it is created for music performance and quality. An protruding aluminium heat sink optimises thermal presentation. Mu-so Qb is cased in a highly complex, 20% glass-filled polymer for robustness, inertness and dampening. At the core is the volume control – made from a solid aluminium ring, which runs the circumference of the touch-panel interface with a patent-pending illumination system.

Everything in Mu-so Qb is controlled by a 32-bit digital signal processor. It controls the music flow to each speaker, drawing on everything learnt from designing the best in-car audio systems for Bentley motors. It features dual EQ settings, producing the best sound quality regardless of whether the unit is placed in the room.


Mu-so Qb off course derives a lot of motivation from the award-winning Mu-so design. However, it was never a case of simply resizing the original. Naim has revolutionised the entire concept by reconsidering each part and perusing every fresh material as they proceeded. Naim’s engineers had to find new ways to create that signature Naim sound within a much smaller footprint, and that is what makes Mu-so Qb genuinely unique.

Through experience, studies, and fine-tuning by ear, Naim built an exceptionally sounding compact wireless system. Mu-so Qb retains all the aspects that made the original design so successful, but attributes to it, its own unique personality. The entire cabinet sits on a lit base of high-grade acrylic that is the ground for the engineering and speakers to radiate.
