Sorry, I'm not getting it. It sounds like what you're saying is that the crossovers introduce a different phase shift for each of the three outputs. So that would mean that the woofer has one phase, mid has another, and tweeter has a third (and thus there are two numbers - the differences - that matter, since we don't care about absolute phase). That sounds right to me, at least to a good approximation (the phase shifts will depend a little bit on frequency even within each band, but maybe not much). So each driver has a different relative phase, but within each band the phase would be more or less untouched. Is that what you're saying? Sorry to be so slow. On the other hand I believe the DEQX is capable of driving all its outputs with the same phase. This is certainly possible in principle - all you have to do is delay each signal by the appropriate amount to cancel the relative phase shifts, and it seems that would be easy to do digitally. -- opaqueice ------------------------------------------------------------------------ opaqueice's Profile: http://forums.slimdevices.com/member.php?userid=4234 View this thread: http://forums.slimdevices.com/showthread.php?t=31590 _______________________________________________ audiophiles mailing list [email protected] http://lists.slimdevices.com/lists/listinfo/audiophiles
