M-Audio SBX Subwoofer
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.
