I received my JBL NSP-1 speaker set and my Kenwood VR-507 receiver the other day. I'm going to be ordering all the cables I'll need to connect everything. BTW, I've decided to go with direct wiring. My center speaker is going to sit on top of the TV. I've read about tilting it down a bit so it's not going over your head. I've also read that the fronts should be ear level. Should they angle in at all, or fire straight out? I'm not sure what to do with the rears. Should they go 2-3' above the head, or ear level like the fronts? How much extra wire should I leave for each speaker? One other thing I haven't decided on is how I'm going to attach my wires to the walls. I'm not doing anything fancy. I'm just going to run them up along the corner on the outside of the wall. Any suggestions for any of the above would be greatly appreciated.
