About the Naim Mu-so Qb

High-performance sound
High-performance sound

Five custom speakers, each individually amplified, plus two passive bass radiators deliver exceptional sound over a wide area.
The distinctive styling of the Naim Audio Mu-so Qb tells you this is more than just a stand-alone wireless music system — and the sound confirms it. Whether you prefer high-resolution audio files, such as those available through HDtracks, the built-in Spotify® Connect, or TIDAL's lossless streaming service, you're in for a rich listening experience. Mu-so Qb is a great system on its own, and can also be part of a Naim multi-room audio system.
Quality construction
The Mu-so Qb features two micro-fiber tweeters and two custom midrange speakers, angled for full, spacious sound. The bass driver is reinforced by two passive radiators for strong, clean bass. Each woofer and tweeter is powered by its own 50-watt amplifier, and the bass driver is powered by a 100-watt amplifier. Separate amplification ensures minimal cross-interference and clean, accurate sound. And with 300 watts total system power, the Mu-so Qb can easily fill the room with clear, lifelike music.
The Mu-so Qb's built-in 32-bit digital signal processor controls the flow of music information to each speaker. Two EQ settings tailor the sound for placing the Mu-so Qb either close to or well away from walls or corners.
Built-in Bluetooth with aptX®
Stream music wirelessly from your smartphone or tablet to the Mu-so Qb via Bluetooth. The system includes aptX audio coding, an advanced type of Bluetooth wireless streaming that retains virtually all the detail of the audio signal it carries.
iOS and Apple AirPlay options
The Mu-so Qb is also AirPlay-compatible for convenient wireless playback from your iPhone®, iPod touch®, iPad®, or computer running iTunes®. And with the Naim app on your Apple portable, you can use Rovi to discover new music and artists based on those you already like.
Multi-room audio with the Naim app
The Mu-So Qb comes with its own remote for convenient control. And with the Naim free control app downloaded to your smartphone or tablet, you have even more options. You can control up to five Mu-so and Mu-so Qb components to create a multi-room audio system. Remotely control your Mu-so Qb components through your home Wi-Fi network. Group your connected speakers so that the same song plays throughout the house, or only on certain speakers. Or even have every speaker accessing a different source and playing a different song. You can also build playlists with the app, and browse thousands of internet radio stations.
Innovative design
The Mu-so QB features a top-mounted touchscreen controller. You can easily adjust volume, play, pause, or skip tracks. The cabinet rests on an acrylic base that dampens vibrations. An aluminum heat sink in the rear keeps the system running cool for optimal performance. And the Mu-so Qb's cabinet is made from a 20% glass-filled polymer to deaden unwanted vibration and ensure optimal acoustic performance.

Features
Custom-Engineered Sound: The Naim MU-so Qb incorporates five drivers, offset and angled perfectly to create exceptional soundstage imaging. In this five speaker arrangement there are two 1" microfiber dome tweeters and two 2.5" midrange drivers, all four driven by 50W amplifiers, with rare earth magnets and copper-capped poles for even greater accuracy. The fifth driver is a custom-made 5.75" x 3" oval woofer that's driven by a 100W amplifier to create an astonishing bass sound for a system this size. Two side-firing pistonic passive 5.8125" x 3.375" oval bass radiators work alongside the custom-made woofer for even lower bass frequency reproduction. Combined, the MU-so Qb can generate an incredible 300 watts of room-filling sound.
- Custom Built Tweeters: Microfiber soft-dome tweeters were selected for their stiffness and dampening qualities.
- Custom Made Midrange Drivers: The custom midrange drivers provide crystal clear speech and power vocals. They've been carefully positioned to evenly disperse sound.
- Mono-Woofer + Dual Bass Radiators: The MU-so Qb pairs a mono subwoofer with two side-firing bass radiators for deep, accurate bass response from a compact speaker system.
32-Bit DSP: 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 Naim's listening room, it controls the flow of music information to each speaker. 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.
- Room Position: Room position enables adjustment of the Mu-so Qb's tonal balance to compensate for the proximity of walls and other large surfaces. If speaker system is placed on a shelf, for example, tonal adjustment can be useful in reducing the bass boost that naturally results from such a location.
- Loudness: Loudness applies a bass boost that decreases as volume is increased. By compensating for the ear's reduced bass sensitivity at low volume levels, loudness compensation can make low volume listening more satisfying
Rigid Enclosure w/ Extruded Aluminum Heat Sink: The enclosure is made from a 20% glass-filled polymer, chosen for its strength, rigidity, and dampening. On the back of the speaker enclosure is an extruded aluminum heat sink which maximizes thermal performance.
Wired or Wireless Network Connectivity: The Naim MU-so Qb is fitted with a RJ-45 Ethernet jack (10/100Mbps) and features built-in WiFi (2.4GHz, 802.11 b/g) for a wired or wireless connection to your home's network. Either connection allows you to connect to your home's network router and internet provider for access to select Online Music Services, UPnP music servers, and AirPlay.
Note: The MU-so Qb supports up to 24-bit/192kHz high-resolution audio over a wired Ethernet network connection, but only up to 16-bit/48kHz over a wireless WiFi network connection.
Naim App for Apple iOS & Android: The Naim Audio app, available for Apple iOS 7.1+ and Android 4.0+ devices, provides simple yet comprehensive control over both your music and the network-connected Naim MU-so Qb wireless speaker and other network-enabled Naim wireless speakers (sold separately). The Naim App provides comprehensive access to Mu-so Qb setup parameters, plus volume adjustment, play/pause/skip tracks, scroll through album art, create playlists, and store favorite radio stations to be easily accessed later. More features & controls include -
- Input selection
- Volume, EQ, & Loudness settings
- Full album & cover art support
- Build & edit playlists
- Browser your UPnP music library with album art support and playback control
- Browse, search, and select Internet Radio stations; plus save & select presets (up to 40)
- USB/iPod browsing and playback control
- Multiroom support including "Party Mode" and group volume control (Apple iOS only).

Notes:
- Only one Naim App from one mobile device can be connected to a single Mu-so Qb speaker at any time.

You can stream a variety of compressed, lossless, and high-res music files. UPnP file browsing can be carried out using the Naim App. Once playback has been initiated by a play command on the Naim App, the Mu-so touch panel, play/ pause, next and previous controls can also be used to control playback. Supported music file formats include -

Spotify makes it easier than ever to discover, manage, and share music with your friends. You can browse music by artist, album, track, or most popular; and create your own music library with customized playlists. Spotify Connect can be selected from the Naim App, but will also select and play automatically when the Mu-so Qb receives a Spotify Connect stream initiated from the Spotify app on your Apple iOS/Android device or Windows/Mac computer.
- Tidal: The Tidal lossless streaming service is integrated into the system for an immersive, high-quality sound experience. Tidal is a global streaming service that offers over 30 million songs in high-fidelity CD sound quality. Tidal has two pricing tiers; either $9.99 or $19.99 a month. Both pricing levels allow you to access Tidal's entire music library. The $19.99 tier has the added benefit of high-fidelity sound at CD-level quality.

You will still use your Bluetooth device for advanced music browsing and to view song/artist info.

Fantastic sound. Bought this for my gf and unlike the one I bought for myself two years ago, which dropped out on WiFi and required cable connection, she is having no such problems.
