B52 LX18AV3 Self Amplifed Powered Folded Horn Subwoofer

The LX-18AV3 is powered by B52's 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 Neutrik output on the amplifier panel. Get one active and one passive - connect them together and feel the walls shake!

All B-52 folded-horn cabinets are loaded with the new B-52 18-220X subwoofer which provides high-power handling, great efficiency, very low distortion and accurate sound reproduction. Key features include: 4-inch "inside/outside" voice coil wound on both sides of the glass fiber coil former, providing more effective cooling through greater air contact. The light weight and robust cast aluminum frame is shaped to minimize reflections on the back of the cone. The entire loudspeaker is designed to work as a "heat sink" for extreme cooling efficiency. The advanced magnet topology ensures an even distribution of magnetic flux throughout the whole magnet assembly, resulting in symmetrical motor movement preventing stray flux which can cause interference. The glass-fiber impregnated cone incorporates a sealed surround and added edge-damping to greatly reduce the occurrence of unwanted cone resonances. The vented magnet ensures constant air circulation to drive heat away from the magnet assembly

The 18" subwoofers are housed in a compression chamber that minimizes the excursion of the driver while maximizing the subwoofers' output. The optimally-sized acoustic aperture of the compression chambers forms the throat of the horn and helps force the air at an increased velocity and pressure. The compression chamber optimizes the horn's output, allowing for amazing output levels.

The new aluminum heatsink design dissipates heat in the cabinet's compression chamber. This provides increased thermal power handling, decreased power compression, increased output and cooler long-term operation.

Can this be combined with the B-52 LX-1515V3 speaker without any addition amps?
null on Apr 24, 2012
BEST ANSWER: The LX-18AV3 has a built in crossover, so if you added the LX1515V3, it wouldnt be able to provide you with full range sound, only the bass frequencies.
