Key Features and Technologies
Dolby Atmos 7.1.2 support is the Hekla's core feature. This means seven main channels, one low-frequency channel, and two height channels for a 3D sound field.
The system supports high-resolution audio playback up to 24-bit/96 kHz. Streaming services, internet radio (including Naim Radio), and podcasts are available through the Focal & Naim App.
Adaptive audio modes allow you to customize the sound to your room. Presets are available through the app: Movie, Music, and Focal's Sphere mode—a special mode for maximum immersion.
Audio Modes
Focal's Sphere mode is a proprietary spatial sound technology. It creates a surround sound effect even with content originally recorded in stereo.
Movie and Music modes optimize the frequency balance for the respective content. Movie emphasizes dialogue and effects, while Music emphasizes detail and soundstage.
Settings are accessible via the app, which also allows you to control multiple Focal and Naim devices in Multiroom mode.
Design and Construction
The Mu-so Hekla is housed in a minimalist enclosure that blends into any interior like a soundbar, but surpasses traditional soundbars in its acoustic architecture.
The drivers are precisely angled to create a sound field around the listener. The rear panel houses a heatsink and Wi-Fi module.
Focal positions the Hekla as an exclusive product: the system is sold exclusively through authorized Focal Powered by Naim boutiques, where you can try it before you buy.
Sound Quality and Experience
The Mu-so Hekla delivers powerful, rich sound with impressive detail. The system is capable of reproducing both cinematic soundtracks and high-resolution music with noticeable accuracy.
Low frequencies are well controlled, without blurring. Midrange frequencies are natural, with clear dialogue. High frequencies are detailed without harshness.
The Dolby Atmos effect works convincingly: sound objects are positioned not only horizontally but also vertically. This is especially noticeable in scenes with flying objects or rain.
Price and Availability
The Mu-so Hekla will be available in Q1 2026. The system is priced at $3,600 in the US, €3,300 in Europe, and £3,000 in the UK.
This places the Hekla in the premium segment, where it competes not with mainstream soundbars, but with hi-fi components and mid-range home theater systems. The system is sold exclusively through authorized Focal Powered by Naim boutiques, where audition bookings are available. This allows you to evaluate the sound before purchasing—a critical feature for a product in this price range.
Who is the Mu-so Hekla for?
The Focal Mu-so Hekla is a solution for those who value sound quality but don't want to deal with a complex system consisting of a receiver, individual speakers, cables, and calibration.
The system is suitable for owners of medium-sized rooms (living rooms up to 30-40 square meters) where aesthetics and minimalism are important, but serious performance is also required.
Hekla is aimed at audiophiles and movie buffs willing to invest in a premium single-box solution. It's not a replacement for a budget soundbar—it's an alternative to a multi-component system.
Advantages and limitations
Comparison with Naim Mu-so Predecessors
The original Naim Mu-so line was focused on stereo music and lacked Dolby Atmos support. Mu-so 2nd Generation, introduced in 2019, focused on hi-fi streaming.
The Focal Mu-so Hekla is an evolution of the concept toward home theater. It features 15 speakers versus previous solutions, Dolby Atmos 7.1.2 instead of stereo, and 660W of power for surround sound.
Essentially, Hekla is a new product, not just an update to Mu-so. It combines Focal's acoustic philosophy with Naim's electronic platform, creating a hybrid system for movies and music.
