Thanks... sure appreciate the help.
I've not yet moved in, (and house is out of state), but going by memory here are the answers to your questions:
1) Approx 10 pairs of speakers.
2) on-wall already
3) Re: the sub, I think it is the Klipsch Synergy Sub 10 (but might've been the Sub-12)
4) No control panels that I saw.. other than Klipsch sub-wolfer, the rest appeared to be Bose Cube Speakers.
5) Home owner had whole system set-up and is just leaving the speakers for me.
Thank You.
