Answer
The WL2082 (ILA) speaker, when used in TriAmp mode, has the following basic crossover frequencies:
LF
- HPF 70Hz Butterworth 24dB/oct
- LPF 400Hz Linkwitz-Riley 12dB/oct
- LPF 1.5kHz Linkwitz-Riley 12dB/oct --secondary to remove potential crossover in HF band
Low/Mid
- HPF 70Hz Butterworth 24dB/oct
- LPF 1.5kHz Linkwitz-Riley 12dB/oct
HF
HPF 1.5kHz 24dB/oct Linkwitz-Riley
Note
Some QSC amplifiers and also the applicable speaker components in Q-SYS have a number of other filters and FIR, all applied with intrinsic correction. For best response from the speaker, one of these products is recommended.
