I am in the process of setting up a new system, I currently have a denon 3802 reciever running energy veritas 2.3 mains, a veritas 2.0c center, I am looking to add 4) veritas 2.0r surrounds, my questions are, 1. What is the best placement for these speakers (height, angle, depth) , 2. How to set them as they have dipole/bipole switches, 3. If I want to go 7.1 in the future how will these speaker placements affect my next upgrade (I am not thrilled with the thought of patching holes in the walls) 4. Do you think the energy rears are my best choice? I am thrilled with the sound of my fronts so they seem like the logical choice, My room dimensions are 13 wide x 18 deep (tv is on a 10 wall), any help would be greatly appreciated!
