B-52 ACTPRO18S 700-Watt Powered 18" Subwoofer - Cast-Framed - Detachable Casters

For those that demand to both hear and feel the bass, the Actpro18S is the ideal active subwoofer. Powered by B-52's 700W proprietary Class-G amplifier, the Actpro18S delivers deep, rich and controlled bass through the custom SP-1804 cast frame 18" subwoofer. The Actpro18S features a built-in third-order crossover with High-Pass and Full-Range outputs, allowing easy expansion of your Actpro system. Heavy-duty detachable 3" casters included.

The Actpro Series is a line of advanced, 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.

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 powerful Actpro18S 18" subwoofer includes detachable 3" casters.

Can it be used with the matrix 2000 system, cause i fried my crossover in the base cab on friday and i want to get this if it works with the speakers I already have?

output on your mixer.
What's max SPL for B52 ACTPRO 18" powered subwoofer?
Dat L on Jan 27, 2017

Hope that helps!
will this sub work with EV powered sub 18inch live series
franny on Jan 30, 2012
BEST ANSWER: Yes, just use the line out of your EV and an XLR cable and plug it into the B52. Since they have their own amps you don't have to worry about messing anything up.
What is HP OUTPUT, how is this used. I use 2 ACTPRO-18, along with ACTPRO-15'S. Should I have the 15's with the bypass on or off?
Paul on Apr 25, 2011
BEST ANSWER: HP output stands for high pass output. This lets the high frequencies pass and not the low ones. So If you have your ACTPRo-18's plugged into th HP output it will only supply them with the higher frequencies. As for the bypass you would have to experament and see what sounds better.
Can it be integrated with the matrix 2000 system I blew the crossover on Friday to just the sub and need to know if i can still hook up the satelites to it? need to know ASAP I have three shows this coming week????

null on Mar 6, 2010
BEST ANSWER: It can be used in conjuction with the Matrix 2000 however the built-in amplifier of the Actpro-18s is designed to only have enough power for the unit itself therefore any integration with other speakers would require seperate and adequate amplification.
Can you power a passive 18s sub with this amp?
null on Mar 5, 2010
BEST ANSWER: The amplifier built inside this subwoofer is designed only to power the subwoofer itself and no other subwoofer (or speaker).
does it include a cover bag
null on Feb 18, 2010

Powerful active sub
Pros: Easy To Set Up,Great Sound Quality,Good Power Output,Attractive Design

I've been DJing for a long time. I've seen and heard terrific speakers; Mackie, JBL, Peavey, Yamaha, and Cerwin Vega. These are all very good speakers, but for me, 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. The 18's are everything you could ask for in a powered sub, and then some. You can feel the lows in your feet. Dishes rattled when I hooked them up at home. 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. No problems so far with thermal overheating. The heat sinks 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 clear, crisp sound reproduction and a rugged build. B-52 delivers both. These speakers are solid. No plastic molds here. They are not light weight toys. Bring a friend to help load these monsters.

great sound good sub
Pros: Great Sound Quality

Good Subs!
Pros: Good Power Output,Great Sound Quality,Attractive Design,Easy to Mount,Easy To Set Up

I just got one of these last month and I'm about to get another one of these. Looking forward to be able to use the High pass filter for this series because I already have two ACTPRO 1515's. All around they aren't too heavy and they kick pretty well. I originaly had a B52 Matrix 2000 which I still have but that setup is what made me stick with B52 on this. You can't get better sign for the price, and made in the good old US of A.
