Unity Audio is a British loudspeaker manufacturer based in Little Walden, Essex, designing and building active studio monitors and hi-fi speakers in the UK. The company was founded by Kevin Walker in collaboration with studio designer and acoustician Kevin van Green, with custom Class A/B discrete amplification originally developed by Tim de Paravicini of Esoteric Audio Research. From the outset, the company committed to a sealed-cabinet philosophy built around Baltic Birch plywood enclosures rather than MDF, aiming for tighter transient response and more controlled low-frequency behavior than ported designs allow.

The brand is best known for its 'Rock' family of nearfield and midfield monitors, including The Mini Rock, The Rock MK-III, and The Super Rock, alongside the larger Boulder MK-III and Mini Boulder midfield/main monitors. Other models in the range include The B.A.B.E. DSP, The Avalanche MK-II DSP, The Monolith, and The Lisson Grove hi-fi loudspeaker. Many models are offered in both passive analog and DSP-equipped variants for room correction and tuning.

Unity Audio occupies a boutique niche in the professional monitor market, with products distributed through specialist pro-audio dealers and used in mixing, mastering, broadcast, and post-production rooms as well as high-end domestic listening setups.

Unity Audio has 3 products cataloged on Equipboard, including Active & Passive Monitors and Studio Subwoofers.
