What I can do is disconnect my two lower M22' mains. (I have 2 m22 mains. Upper and Lower.) Then connect the center channel output from the receiver to one of the Lower M22 mains. If I no longer hear the upper bass, then I will have proved my point. If I do hear the upper bass, I'll never mention it again. Fair?
Also, I'll try and test this using a frequency sweep that does one freq at a time and see if I can measure a difference. This might not tell me anything since there is a gap between each frequency.
Actually, all I have to do, is listen and measure with, and without, the VP160 being plugged into the mix. There is still an M80 plugged into the center channel.
