B-52 ACTPRO-18S Powered Subwoofer

The new ACTPRO Series is an advanced line of made in the USA powered loudspeaker systems that offer the sonic accuracy, power and reliability demanded by today’s professional performers. Fueled 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.

The ACTPRO18S subwoofer features a built-in third-order crossover with High-Pass and Full-Range outputs, allowing easy expansion of your ACTPRO system. All ACTPRO cabinets are built in the USA at our state-of-the-art Los Angeles manufacturing facility. Each model features rugged birch plywood construction, durable, black Warnecke paint finish and 16-gauge wrap-around steel grilles, all designed to withstand the abuse of the road. Custom Celestion loudspeakers and compression drivers are used in all full-range models. The ACTPRO12M is designed to be used as a main speaker or sit as a dedicated stage monitor. The powerful ACTPRO18S 18” subwoofer includes detachable 3” casters.
