Fuelled by B-52’s ultra-efficient Class-G amplifiers, ACTPRO systems deliver rich, clear sound at extreme SPLs. ACTPRO amplifiers employ sophisticated circuitry including acoustically tuned 4th order crossovers, four stages of equalization, a built-in intelligent compressor\/limiter and short circuit\/over-current protection. An extra high current output stage allows for uninterrupted extended play without risk of thermal shutdown. ACTPRO full-range amplifiers are bi-amped with fully discrete output stages.\u003c\/div\u003e \u003cdiv\u003e \u003c\/div\u003e \u003cdiv\u003eThe ACTPRO18S subwoofer features a built-in third-order crossover with High-Pass and Full-Range outputs, allowing easy expansion of your ACTPRO system.
