Roots in Rave and Club Culture

Sound with pedigree

Our story started in the 1990s, building sound systems for raves and installing systems in London's West End clubs, including reinforcement systems for big nights at Maximus in Leicester Square. Our systems have been used by names including Carl Cox, Colin Dale, Colin Faver and the Rampage crew. Decades of testing speakers taught us one lesson: you do not always get what you pay for. Now we have speakers manufactured to our own specifications, to give you more than you expect for your money.

Speaker facts

+3 dBDoubling your amplifier power only adds 3 dB. A more sensitive driver often beats a bigger amp. 4×For the same loudness, a cone has to move four times as far for every octave lower. +6 dBTwo identical subs side by side give up to 6 dB more bass than one. 0.4%A copper voice coil's resistance rises about 0.4% per °C, which is why hot drivers go quiet.
