M-AUDIO Studiophile SBX - Manual (Page 10)

Setting the Subwoofer LPF and the Satellites HPF
The fundamental concept behind the Stereo Bass Management System is to
isolate the upper and lower frequency ranges and direct them respectively to
the component best suited to reproduce them. In order to accomplish this, the
SBX utilizes a crossover network to determine how different frequency ranges
are distributed to the subwoofer and satellite monitors.
