<font color='#000000'>I have seen some specs of speakers in a set designed for 5.1 configuration. I noticed the center speaker uses 1st order crossover while the main front speakers uses 2nd order crossovers. I understand such crossovers have a 90 and 180 degree phase shifts, respectively. Does that matter at all?
Also, I've noticed that some 3-way speakers use 1st order between tweeter and mid-range, but uses 2nd order between mid and woofer. IS that ok?</font>
