About the Naim Mu-so 2nd Generation
High-resolution audio reimagined
High-resolution audio reimagined
Naim Audio's original Mu-so wireless music system was an impressive high-performance music system. The completely redesigned Mu-so 2nd Generation raises the bar. It plays high-resolution audio files such as those available through HDtracks, music from your Spotify® playlists, or TIDAL's lossless streaming service with amazing accuracy. Stream wirelessly straight from your smartphone via Bluetooth. The Mu-So 2nd Generation can also be part of a multi-room audio system — either through the Naim app, Apple AirPlay 2, or Google Chromecast.
High-performance speaker drivers
The Mu-so 2nd Generation features six custom-designed built-in speakers for full, accurately detailed sound. It has two silk dome tweeters for clear highs, two dedicated drivers for articulate midrange, and two oval bass drivers in a ported enclosure for clean, robust lows.
Each speaker is powered by its own 75-watt Class D amplifier, ensuring minimal cross-interference and finely detailed sound. And with 450 watts total system power, that sound can easily fill even large rooms without distortion.
A powerful processor for speedy performance
The system features a multicore digital signal processor (DSP) that provides 2,000 MIPS (million instructions per second), more than 10 times faster than the original Mu-so's processor. The result is better audio accuracy and detail. A new limiter algorithm carefully controls the movement of each of the speaker drivers at high volume levels. This prevents the speakers from being overdriven to keep the sound clean and accurate, even when you crank up your music.
Multi-room audio with the Naim app
The Naim mobile app lets you control up to five Mu-so speakers or compatible Naim components to create a multi-room audio system via your home Wi-Fi® network.
Group your connected speakers so that the same song plays throughout the house, or only on certain speakers. Or play a different song from a different source in each room. You can also build playlists with the app, and browse thousands of internet radio stations.
Compatible with Apple AirPlay 2
Built-in Apple AirPlay 2 technology lets you stream audio directly from your iPhone®, iPad®, or Mac® computer. That includes soundtracks from YouTube® videos and Netflix movies. 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.
If you subscribe to Apple Music®, you can do even more. Use Siri on your iPhone, iPad, or Apple TV 4K to control Apple Music with voice commands. Tell it what selection or playlist to play — and which compatible speakers or components you want it to play through.
Google Chromecast built-in
The Mu-so 2nd Generation has Google Chromecast built-in. That means you can wirelessly join it to other Chromecast built-in speakers on your Wi-Fi network to create a multi-room wireless audio system. With the Google Home app on your smartphone or tablet, you can call up playlists and access streaming services such as Spotify Premium, TIDAL, Pandora®, Google Play Music, Tunein, and iHeartRadio.
If you want to go hands-free and app-free, add a Google Assistant voice controller. That way, you can control your Mu-so 2nd Generation by simply saying, "OK Google, play Pat Metheny in the den."
The Mu-so 2nd Generation has an elegant anodized aluminum casing with extruded heat sinks to keep the system running cool. Its fully redesigned cabinet features rigid bracing to eliminate sound-muddying vibrations.
The top-mounted touch-sensitive dial and buttons provide an extraordinary amount of control. It's easy to adjust volume, or play, pause and skip tracks. You can also cycle through input sources, directly access favorite presets, create a group of zones with other Naim products, and more.
Roon-compatible for serious music lovers
The Mu-so 2nd Generation is also compatible with Roon, a subscription digital music player for your smartphone, tablet, or computer. It gives you multi-room audio playback for all your Chromecast-compatible devices and more. Roon accesses your digital music collection from your iTunes library or NAS drive. It also works with your TIDAL subscription. Roon lets you do deep dives into your music, showing artist bios, photos, reviews, and lyrics. Roon can also suggest other artists and songs based on your selections, making it easy to discover new music you'll enjoy.

Optimized Speaker Drivers: The Mu-So 2 features improved and highly optimized speaker drivers through a joint development project between Naim and Focal R&D departments. The Naim Mu-So 2 houses two 1" soft dome tweeters, two 2.5" custom midrange drivers, and two 5.25" x 3.0" oval woofers for room-filling, full-range sound.
- Soft Dome Tweeters: Soft dome tweeters were chosen through listening tests to replace the traditional metal cones found in many wireless speakers for better smoother high frequencies and better overall sound quality.
- Custom Midrange Drivers: Custom midrange drivers provide crystal clear speech and powerful vocals. Positioning them at the outermost edge of the cabinet aided in even sound dispersion.
- Dual Woofers + Bass Port: Two large custom bass drivers are supported by a sophisticated porting system with an outlet at the end of the speaker cabinet. It was carefully designed to move large volumes of air with low turbulence for richly textured, low distortion bass.
DSP Controlled Amplification: Six 75 watt Class D amplifiers, one for each of the six custom-designed drivers, produces a total of 450 watts of power for dynamic sound. An all-new multicore Digital Signal Processor (DSP) delivers higher performance, providing 2000 MIPS (Million Instructions Per Second) compared to the original Mu-So's single-core, 150MIPS DSP. The result is superior music accuracy and incredible audio detail. In addition, a new limiter algorithm keeps each drivers' movement under control when at high volume levels (only active at extreme volume levels) which helps to retain your music's clarity and increases long term reliability.
- Room Compensation: Room Compensation enables adjustment of the Mu-So 2'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
High Quality Cabinet Construction: The Naim Mu-So 2 features a premium aluminum casing in a new burnished grey finish. Its cabinet design has been re-engineered to create 13% more internal volume, enabling bigger, better bass. Both the cabinet bracing and baffle moulding have been redesigned for improved rigidity, which suppresses and controls vibrations. The distinctive heat-sink fins are more compact, while still being ultra-effective, and continuing to feature Naim patented technology that discreetly incorporates the WiFi antenna.
Multiroom Ready: The Mu-So 2 works brilliantly on its own or as part of a multiroom music setup. There are three easy ways to create a multiroom audio system in your home.
- Naim App: Combine it with other networked Naim products (including 1st and 2nd Generation Mu-so and Mu-so Qb) via the Naim app (for Apple iOS 9.3+ and Android OS 5.0+). Up to five Naim products can be synced together.
- AirPlay 2: Pair it with other AirPlay 2-compatible wireless speakers via the Apple Home app on your Apple iOS device.
- Chromecast: Pair it with other Chromecast speakers and devices via groups controlled by the Google Home app on your Apple iOS or Android OS device.
Mounting Options: The Mu-So wireless speaker is designed to be located either on a table, a furniture unit, or a wall shelf. If a shelf is to be used, be sure that it is able to support the full weight (28.7 lbs) if the speaker system. The Mu-So 2 does not provide a bracket, key-hole slots, or threaded inserts to wall-mount the speaker system.
