Focal Mu-so Hekla - Grey

Description

Advanced Acoustic Engineering and Driver Array

Developed through a close collaboration between Focal and Naim engineers, the Mu-so Hekla features a meticulously structured cabinet housing 15 individual speaker drivers. The front array utilizes three 13 x 6 cm racetrack-shaped woofers dedicated to solid low-end delivery, accompanied by two 6 cm midrange drivers and two 25 mm tweeters. To reproduce the height and surround channels of object-based audio formats, two pairs of 4 x 7 cm full-range drivers are mounted on the sides and top panels. This sophisticated layout yields an impressive frequency response spanning from 30 Hz to 20 kHz.

High-Efficiency Amplification and DSP Processing

Driving this complex transducer array is a total of 660 W of Class-D power amplification managed with precise control. The three central bass drivers receive 60 W each, while the remaining 12 drivers are assigned 40 W of discrete amplification apiece to maintain excellent transient response and prevent distortion at peak output levels. Running on the Naim Pulse platform, the integrated DSP utilizes proprietary Sphere modules to execute advanced beamforming and crosstalk cancellation, accurately placing dialogue and sound effects in the listening space.

Modern Connectivity and High-Resolution Streaming

The Mu-so Hekla integrates seamlessly into modern smart homes using dual-band Wi-Fi 6 or a physical Gigabit Ethernet connection. It natively supports Apple AirPlay 2, Google Chromecast, and UPnP protocols, allowing direct playback via Tidal Connect, Spotify Connect, and Qobuz. Physical source integration is highly versatile, featuring an HDMI eARC input with CEC support for direct television connection, an optical Toslink digital input, and a dedicated stereo RCA subwoofer output for external bass reinforcement.

Custom Intelligent Calibration and Refined Finish

To counteract room-induced acoustic anomalies, patented ADAPT (Adaptive Acoustic Personal Tuning) technology calibrates output by calculating distances to nearby walls and ceilings via the Focal & Naim app. The system's exterior pairs minimalist aesthetics with premium construction, featuring a brushed and sandblasted black aluminum casing alongside anodized rear heatsinks. The tactile top interface features a smooth-scrolling rotary volume dial with an integrated proximity sensor, providing intuitive control over source selection and presets.

Common Questions

Why choose this product?

The Focal Mu-so Hekla unites premium acoustic design with contemporary streaming technology to form an uncompromising single-box audio solution. Its discrete 660 W amplification and 15-driver configuration generate authentic Dolby Atmos immersion with profound low-end extension. It represents an ideal selection for audiophiles who demand the detailed resolution of traditional hi-fi without the extensive footprint of multiple components.

Which high-resolution digital audio formats are supported over the network?

The network streamer handles a comprehensive suite of premium studio-grade files. It decodes two-channel WAV files up to 32-bit/384 kHz, alongside FLAC, ALAC, and AIFF files up to 24-bit/384 kHz. Native playback of DSD64 and DSD128 streams is also fully supported for high-fidelity digital collections.

Can this system be integrated into a wider multiroom network?

Yes, the Mu-so Hekla can easily synchronize with other compatible components in your home. Through the Focal & Naim app, users can group up to 32 network streamers or wireless speakers from either brand to play audio simultaneously across different zones.

Is an external subwoofer required to achieve deep bass?

With a low-frequency point extending down to 27 Hz at -6 dB through its three racetrack woofers, the system provides highly authoritative and controlled bass on its own. However, for exceptionally large listening areas or viewers wanting maximum low-frequency impact during cinematic viewing, the physical stereo RCA output allows for straightforward connection to an external powered subwoofer.
