B-52 ACTPRO-12M Main/Monitor 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.

Loudspeaker Specifications

Type
This is the type of professional loudspeaker. Active loudspeakers have a built-in amplifier to power the speakers. Passive loudspeakers require an external amplifier to be properly powered.
Active
High Frequency Driver Size
This is the size of the high frequency driver. Common sizes include 1", 1-1/2" and 2".
1-3/4"
Low Frequency Driver Size
This is the size of the low frequency driver. Common sizes include 10", 12", and 15".
12" Driver
Frequency Response
The range of frequencies the speaker will reproduce (lowest frequency to the highest). Bigger is better, meaning the wider the range, the better. The optimal range is 20 - 20,000 Hz (which is the range of human hearing).
58 - 18000 Hz
Sensitivity
An efficiency or sensitivity rating tells you how effectively a speaker converts power into sound. The higher the number, the more efficient the speaker and the louder it will play with the same input power. An efficient speaker helps you maximize your available power. Most sensitivity ratings measure the speaker's output with 1 watt of input, 1 meter from the speaker. Some speakers' sensitivity is measured with 2.83 volts of input, instead of 1 watt.
 
Efficiency (1w/1m) is not an accurate indicator of a subwoofer's output capability and should not be used as a comparison to other speakers or subwoofers to determine which one is "louder".
98 dB
Maximum Sound Pressure Level SPL
This is the maximum Sound Pressure Level (SPL) of the professional loudspeaker. The higher the SPL rating, the louder the monitors are able to go.
