Inside the system

Project Audio’s installation combines Tannoy Westminster Royal-class towers and Super Tweeters with four TPI UC15G units, two beneath each Westminster. Tannoy Autograph Minis provide fill, with Luxman M-10X and 509Z electronics, FFA/NST amplification and DSP crossover and time alignment. Two Technics SL-1200G decks feed an Isonoe 420 rotary mixer. Separate listening stations use an SL-1210MK7, Leak Stereo 130 and Grado SR325x headphones. Townshend Seismic Isolators are used beneath the speaker stacks, linking the large-format loudspeaker arrangement with mechanical isolation.
