Audio enthusiasts, mark your calendars. Premium Sound is bringing some serious firepower to the StereoNET HiFi Show 2025, and the star of their display is guaranteed to turn heads – the brand new Focal Diva Mezza Utopia speakers, making their Australian debut.
At $110,000, these aren’t your typical bookshelf speakers. The Diva Mezza Utopia represents Focal’s latest breakthrough in wireless high-fidelity audio, packing four innovative 8-inch woofers and delivering a hefty 500 watts of power per speaker. These active floorstanding speakers are engineered to fill rooms up to 100 square meters with pristine sound, making them perfect for Australia’s luxury home audio market.
“We’re thrilled to bring this extraordinary speaker system to Australian audiophiles for the first time,” says Rob Bergervoet, Store Manager at Premium Sound. “The Diva Mezza Utopia perfectly embodies our commitment to offering the absolute best in high-end audio technology.”


What Makes These Speakers Special?
The technical specs read like an audiophile’s wish list. Each speaker features 500W of Class A/B amplification with dual power supplies, Pure Beryllium inverted dome tweeters, and Focal’s signature ‘W’ cone drivers. But perhaps most impressive is the Ultra Wideband (UWB) wireless technology that delivers up to 96kHz/24-bit resolution – that’s studio-quality audio without a single cable.
The system also includes ADAPT (Adaptive Acoustic Personal Tuning) technology that automatically adjusts to your room’s acoustics, plus compatibility with major smart home platforms including Control4, Crestron, Savant, and RTI.
Building on the success of the original Diva Utopia, the Mezza version increases cabinet volume from 50 to 62 liters and boosts power output by 25 percent. Connectivity options are comprehensive too, with HDMI eARC, TOSLINK, RCA, USB-A, and Ethernet inputs supporting audio formats up to 24-bit/384kHz.
More Than Just One Star Product
Also on display, Premium sound will also showcase the Focal Sopra No.2 speakers, known for their advanced NIC (Neutral Inductance Circuit) motor system and distinctive Beryllium tweeters. These will be paired with Naim’s premium amplification, including the NSC222 streaming preamplifier and NAT250 power amplifier, demonstrating the synergy between these two highly regarded manufacturers.
The complete Focal headphone range will also be on display, from the wireless Azurys models perfect for everyday listening to the flagship Utopia headphones for the ultimate personal audio experience.

Premium Sound recently completed a major renovation in partnership with Focal and Naim, creating dedicated listening spaces designed specifically to showcase high-end audio systems in optimal acoustic environments.
