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.

• Focal & Naim app: Combine it with other networked Naim products (including 1st and 2nd Generation Mu-so and Mu-so Qb) via the Focal & Naim app (for Apple iOS and Android OS). 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.
• Google Cast: Pair it with other Google Cast 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.
