Wiring speaker switches to change orientation of HT speakers
My friend's SONOS:Connect is connected to his multiroom receiver (older Niles 6-room unit) and we're trying to figure out a way to tie it into the in-ceiling home theater speakers. The line-level side of it is easy - just split the output of the SONOS:Connect between the HT receiver and multi-room receiver. On the speaker-level side, ideally when switched to SONOS mode, the left and right rear speakers would function as right channels and the left and right front speakers would function as left channels. The idea is that a Logitech Harmony Hub would be programmed to have both ATM-7's switch to input A to watch TV and input B to listen to SONOS.
I have three questions:
1) Will this actually work?
2) Assuming impedances are matched, is there any reason I can't drive two speakers off one channel of the receiver (the Pioneer manual claims "guaranteed speaker impedance..... 16 ohm to 8 ohm", so as long as the impedance of a single speaker is between 4 and 8 ohm, should we should be ok?).
3) Any issue with connecting 3 speaker cables to a single binding post?
