In Reply to: Since your subwoofer has a low pass crossover, you could make do with a high pass unit posted by lwang on February 19, 2003 at 21:00:57:
Frankly, I think it's a pretty bad idea to try and match a 2nd order high-pass crossover filter to the 2nd order rolloff of you main speakers (if they are truly 2nd order rolloff which is mostly only true for acoustic suspension) and then try to match that mess with the internal low-pass crossover of the sub.For smoothly blending bass frequencies between mains and sub(s), I prefer something like a symmetrical Linkwitz-Riley (zero degree phase offset) crossover with a rather steep 24dB/octave slope.
This equalizes signal amplitude at the crossover frequency, and IMO makes it easier to pick a correct crossover frequency for a specific set of mains and sub(s).
