B-52 LX-18AV3 Active Subwoofer

The LX-18AV3 (active) and LX-18V3 (passive) are the third generation of our powerful folded horn subwoofer design, hailed by music professionals for their reliability, performance and affordability. The V3 is bigger, louder and better. V3 improvements include a larger cabinet with an improved horn design and our new overbuilt class H amplifier. At the heart of these folded horn cabinets is the new 18-220X subwoofer which provides higher efficiency and an ultra-efficient heat management system which keeps the speaker cool even when driven at high SPLs.

The LX-18AV3 is powered by our award-winning 1200-watt class H amplifier. The overbuilt 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 sub. What sets the LX-18AV3 apart is its ability to ALSO power the passive LX-18V3 subwoofer using the NeutrikTM output on the amplifier panel. Get one active and one passive connect them together and feels the walls shake!
