Focal's high-end flagship wireless speaker system is aimed at "demanding audiophiles" and is packed with new technology

Focal has a new flagship active wireless speaker system, and you'd better start saving it you want to get your hands on one.

The new Focal Diva Alta Utopia sits at the summit of the brand's Diva Utopia range, which is made in collaboration with sister-brand Naim Audio. As with the rest of the range, the new system offers built-in amplification alongside wireless streaming powers in a pair of floorstanding speakers – and it's the largest, most powerful and most expensive model yet.

We reviewed the first of the range, the five-star Diva Utopia system in late 2024, and found it a very impressive offering.

Focal pledges that this new flagship Alta Utopia system is "aimed at the most demanding audiophiles looking for an exceptional system", taking the ingredients of the established lineup and elevating them to new heights.

The Diva Alta Utopia features a new generation of the brand's 'Prism' tweeter, a 27mm unit which combines multiple materials for "the perfect balance between lightness, damping and rigidity".

That tweeter is complemented by a reinforced 13cm 'M-profile' midrange driver, with carbon reinforcement and a sealed enclosure that aims to offer a detailed, natural sounding mid-frequency reproduction.

Four 20.5cm woofers in each tower tease a deep and articulate bass, while a 16.5cm 'W' mid/bass driver uses a cone with two sheets of glass on either side of a central foam body, which, says Focal, grants the ideal blend of lightness, rigidity and damping.

The active system packs a huge 600 watts of Class A/B power per speaker, which is distributed over four dedicated amplifiers to provide what Focal says is an "exceptionally wide" sound with "no dynamic compression".

Thanks to the implementation of Naim's Pulse streaming platform, the flagship system can accept high-resolution files up to 32-bit/384kHz PCM. The Diva Alta Utopia uses Focal's 'Ultra Wideband' technology to ensure 24-bit/192kHz wireless support between the speakers, and a hi-res connecting cable is also provided.

'Focal Time Management' tech is integrated, wherein the speakers' drivers are arranged in a curved arc to obtain a more consistent and realistic sound image at all times. This design is in keeping with Focal's Utopia series of passive speakers.

Streaming support is extensive, with UPnP compatibility allowing you to stream digital files across a home network from a NAS unit, and the system is compatible with the most popular platforms, such as Spotify Connect, Tidal Connect and Qobuz. AirPlay 2 and Google Cast are also on board, while aptX Adaptive codec support allows for 24-bit Bluetooth playback from a compatible source.

For physical connections, the primary loudspeaker houses HDMI eARC, optical, USB-C and RCA line-level inputs, and an ethernet port if you prefer a wired connection to the internet. Those physical connections are mounted to a curved heat sink, designed for maximised thermal dissipation, while an aluminium base aims for optimised airflow and better ventilation.

The Focal Diva Alta Utopia is available now, in five distinct finishes: Grey Felt, Ivory Felt, Black High Gloss, Off White High Gloss, and Dune High Gloss.

The price? A rather hefty £165,000 / $199,999 / €190,000 for the felt finishes and £175,000 / $210,000 / €199,990 for high gloss. That's considerably higher than the original Diva Utopia we tested at £29,999 / $39,999 / AU$59,999 per pair.
