B-52 ACTPRO-1515 Bi-Amplified Powered Speaker

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.

Awesome Speakers

September 16, 2011

I've been DJing for a long time. I've seen speakers come and go, but B-52 is the real deal. For the last 5-6 years my main rig was the Matrix 2000. Great plug and play setup. Very dependable. I recently purchased two ACTPRO18S subs and stacked them with a pair of ACTPRO1515's. Thought I had a problem out of the box, but called Ken Heath at B-52 Tech Support, and he talked me through it. Ken really knows his stuff. We swapped a few DJ stories and I was back in business. The 18's are everything you could ask for in a powered sub, and then some. You can feel the lows in your feet. They sound great and can run all night. I'm not talking 5 or 6 hours, I'm talking all night long. They have HP outputs and a 0-180 degree Phase switch. I prefer the 0 degree for positive polarity, but some DJ's like reversed polarity in their subs. The 1515 mains are 2-way full range and can rock most venues, unless your gigs are at Shea Stadium. No problems so far with thermal overheating. The heatsinks are pretty good size. The speakers have a low cut switch, LED indicators, and a ground lift switch. The fronts have a blue LED for flair, but I'm more into great sound reproduction and a rugged build. B-52 knows how to build their speakers for road abuse. These speakers are solid. No plastic molds here. Bring a friend to help load these monsters. -DJ Captain Wild Bill
