M-Audio Studiophile 8S

While the SP-8B offers as much or more bass response as you'll find in any monitors of similar size, the addition of an SP-8S subwoofer puts 120 watts of truly bone-shaking bass in your face. 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 mains. The SP-8S is so affordable that it also makes an excellent companion to other monitors as well. When subwoofers are added to many systems, all frequencies are routed to both the main monitors and the sub. The sub typically has a low-pass filter to roll off the highs-as does the SP-8S. The problem is that both the main monitors and the sub are still trying to put out the same low frequencies, thereby compromising fidelity. M-Audio's Stereo Bass Management System solves that and delivers optimal quality. The SP-8S accommodates the stereo outputs from your mixer, and your main monitors then connect to outputs on the sub. The SP-8S's internal crossover network splits the signal at a user-defined crossover frequency (50-180Hz), routing everything below it to the internal sub and everything above it the main outputs. This significantly improves fidelity because the sub and mains aren't tripping over each other to reproduce the same frequency - and each component only has to reproduce frequencies to which it is ideally suited.
