A final thing to note is you have to be wary of processors that allow you to set different crossover points for different speakers. With the exception of some very high-end processors, you should not use this feature. The vast majority of processors with this "feature" high-pass each speaker's signal at the frequency you specify, and send it to the speaker. This is good. However, to feed the sub, the processor will sum the full-range signals from all the full-range channels and the LFE channel, and then low-pass this signal at the lowest crossover point you set. So, if you have your surround crossover set to 100 Hz and your main crossover set to 40 Hz, there will be a 60-Hz hole in your surround channels' responses. This is not good. THX chose 80 Hz as its bass management crossover point for a reason; trust their research and experimentation.

I picked this up on the Outlaw forum. Is this correct?
