soundhound,
If the triple crossover and trims and such are active during 5-STEREO or 7-STEREO processing, could you use a CD with pink noise or a sine sweep to check the crossover points and LFE/Sub behavior? That would save the kilobuck purchase, or at least delay it a bit...
I wouldn't use either of the 5 or 7 stereo modes, or _any_ other of the DSP modes (PLII, etc) to test response of the system. The reason for this is that there is de-matrixing going on to extract and 'synthesize' more channels from a CD which is a 2 channel source. This processing can, and will effect your measurements.
If you are in fact just setting the crossover from main speakers to subwoofer, this can be done with a sweep test or discrete frequency test. There are some useful test signals on DVDs like Sound & Vision's Home Theatre tune-up, the Avia Guide to Home Theatre, and possibly some others. I find the Sound & Vision DVD very useful, but I don't know if it has a frequency sweep.
What solution were you thinking of buying for a KiloBuck?
