Our new generation of ACT-Series subwoofers are the ultimate solution for low frequency sound reinforcement. These innovative active subs deliver up to 135dB of deep, rich, chest pounding bass. At the heart of the ACT subwoofers is our award-winning 1200-watt class H amplifiers. The overbuilt amp design includes a compressor / limiter, subsonic filter, phase switch, stereo XLR inputs and both full-range and high-pass XLR outputs. The built-in 18dB/octave electronic crossover provides 70Hz, 100Hz and 140Hz settings allowing you to perfectly match your top cabinets to this subwoofer. What sets the ACT-18XV2 apart is its ability to ALSO power the passive ACT-18XSV2 subwoofer using the Neutrik™ output on the amplifier panel. Get one active and one passive connect them together and feel the walls shake!

Active powers the passive
The ACT-18XV2 (active) subwoofer is designed to power an additional passive subwoofer (ACT-18XSV2). The passive subwoofer has the same physical dimensions as the active model. Connecting them together increases the available amp power from 800 to 1200 watts. An additional 3dB SPL boost is achieved if subs are placed near each other.
