CROSSOVER_FOR_20_Hz_SUBWOOFER

Published:2009/6/28 23:44:00 Author:May | From:SeekIC

Used at channel outputs of stereo system when re-producing music down to 20 Hz as synthesized by electronic function generators. Active crossover network drives subwoof er (low-bass loudspeaker) connected in bridgedcenter configu-ration, for handling sounds below range of normal woofer. Crossover consists of thirdorder Butterworth (18 dB per octave) networks providing 20-Hz cutoff along with 100-Hz cross-over. Response of subwoofer should extend one octave above crossover. 0ne advantage of active crossover is freedom from transient intermodulation distortion.-W. J. J. Hoge, Switched-0n Bass, Audio, Aug. 1976, p 34-36, 38, and 40
