9.1.3 SBS Subwoofer with An Electronic Controller
The SBS subwoofer requires a single amplifier channel amplifier. Also required is an electronic
crossover to limit the high frequencies from being reproduced by the subwoofer and a high-pass filter
to prevent subsonic frequencies from overdriving and possibly damaging the loudspeaker.
