No problem.
I am running a Panasonic CP-72. The configuration in the player is all 5 (sorry I did say 4) set for large. So all info including LFE is sent through those channels.
I 'eliminate' the sub out. (In the player menu as well as physically do not connect a Sub input to the 950 from the player).
So now, the crossover in the 950 (switch ON) splits at 80 Hz, anything lower rolling off to the 950 sub output. Anything higher, rolling up to the 5 satellites.
And they are satellites, this is an M&K 750 THX system. Sub is self-powered.
Back to my orignial question, is the phase reversal happening within the 950 Bass Management OUTPUT circuitry, or only on the BM input circuitry? Breaking it down futher, visualize a signal and ground at the sub input to the BM and a signal and ground to the Sub output. Where is the phase reversal actually happening? I am probably over-simplifying the anomaly.
