Be summoned by the sound.

Mu-so Qb is the new compact wireless music system from the engineers behind the award-winning Mu-so. Controlled by a powerful audio brain, Mu-so Qb is alive with custom-made features all designed in our audio laboratories in England. It’s a true feat of sound engineering. From the contours of the glass-filled polymer casing to the bass radiators that help create huge low frequencies – every millimetre of space has been used to great effect. Simple to control and easy to connect, Mu-so Qb delivers a staggering 300 watts of power that unmasks your music with a sound that defies size.

Its advanced yet simple to use connectivity includes Airplay, Bluetooth®/aptX®, Spotify Connect®, TIDAL, UPnP™ (access your stored music), Internet Radio, USB, analogue and digital inputs, Apple iOS and Android App for complete control.

You can also combine Mu-so Qb, Mu-so and other Naim streaming products for the ultimate multiroom experience. Simply sync the units to play the same song beat-for-beat in up to five rooms.

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 four driven by 50W amplifiers, with rare earth magnets and copper-capped poles for even greater accuracy. And 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. When the speakers and woofer combine, Mu-so Qb amplification can generate an incredible 300 watts.

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 system. Fine-tuned in our listening room, it controls the flow of music information to each speaker, drawing on everything we've learned from designing the best in-car audio systems from Bentley motors. It also includes two EQ settings, tailoring the best sound quality whether the unit is 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.

Naim Factory Refurbished

Buying a Naim Factory Refurbished product is a great way to get "as-new" products at a considerable savings. Every product has been thoroughly tested, repaired (if necessary), cleaned and otherwise renewed to original condition. Next it’s repackaged with accessories included. When you consider that a factory-renewed Naim product undergoes such close scrutiny for defects and workmanship, you might actually be buying something that is in many ways better than new. And for your piece of mind and protection, your purchase is covered by a full 2 year parts and labor warranty.

Onkyo, like all electronics manufactures, receives products returned for various reasons. In 2011 consumers returned 17 billion dollars in electronics globally, of which less than 5% were found to be defective! Once a product has been opened it must be resold as refurbished and can’t be resold as new again. The history and reason why a product was returned is not provided to us, thus we can’t provide any additional details regarding its past. All products are processed by Naimcertified technicians, where they are fully tested, repaired (only if necessary), and retested again to ensure the highest quality control. Each unit must pass a complete battery of test before it can be titled a "Naim Factory Refurbished" product.

Most units are Cosmetically in Mint Condition (graded a 9 or higher on a scale of 1-10). Very minor signs of wear (light surface scuffs or minor scratches) may be present, although most units show little or no signs of any usage. We DO NOT sell products that are cosmetically damaged (cracked displays, broken knobs, heavy scratches, or physically abused) unless noted in the description. Unfortunately, we can’t provide actual photos of each unit or pick the best one for anyone, as they are all randomly chosen from our factory sealed boxes.
