M-Audio Studiophile SBX Subwoofer - SUBWOOFER FOR STUDIOPHILE BX8 AND BX5

(This text is machine translated) While M-Audio's BX8s and BX5s offer as much bass response as you'll find in any monitors of similar size, the addition of an SBX subwoofer puts 120 watts behind those low frequencies that you can really feel. In fact, so many consumers have subwoofers that you're not really mixing accurately without having a sub yourself. M-Audio's unique Stereo Bass Management System splits the signal at the variable crossover frequency, routing everything below to the sub and everything above to the satellites. The SBX is so affordable that it also makes an excellent companion to other monitors — from stereo to full surround setups. 100W active bass-reflex subwoofer (for Studiophile BX8 and BX5), with 8 "cone, frequencies from 30 to 180 Hz, XLR inputs (L, R) and balanced / unbalanced 1/4" jack, outputs (L, R, extra sub) Balanced XLR, level, phase, subwoofer and satellite frequency controls, HPF bypass, auto-power and power on / off.
