[QUOTE="GordonW, post: 2793572, member: 568981"] I just don't find fixed-frequency crossovers that useful, in real-world terms. Being able to "dial in" the frequency of the lowpass and highpass seperately, is a BIG deal in getting a system JUST RIGHT. Many times, you can even eliminate the need for an EQ, just by setting the crossover in "creative' fashion (ie, either overlapping or underlapping/gapping frequency ranges)... Another thing that making gaps or overlaps can do- the phase shift and time delay in the crossover region are usable as tuning tools, too. Sometimes, I've actually set a crossover with a DELIBERATE undelap, to increase the phase shift to compensate for path-length differences, and dialed in an EQ to bring the frequencies in-between the gap settings back to flat. It's something you don't want to do in great quantities... but again, it can make the difference between a GOOD system and a GREAT SOUNDING one... Can't really do that with switches, though... Regards, Gordon. [/QUOTE]
