if KCB had said his test revealed a 180 degree shift, i would lean toward the analog crossover as the problem and the switch flipping cure.

the 'possible' scenario i offered IS electrical (with delay, without delay)...not placement...as the problem. placement is a way to test the theory.

in repeating kevin's test, i found the phase difference (less difference than kevin's). i have 2 subs. i placed them equidistant with the front 3 speakers and the difference was reduced.

anyone is free to tell me why that is.
