I have two sofas set up in my veiwing room...one in front of the display and one to the left. I currently have the raer surrounds on either side of the main listening position, but I want to put surrounds on the sides of the sofa on the left. I am planning on using an A/B speaker switch between the receiver and the 4 surrounds. I am using the Kenwood HTB-504 (VR-507 receiver). I am using the front speakers that came with the system as my main surrounds and the rear speakers for the "secondary" surrounds (I already had a pair of Pioneer towers for the fronts). My question is, will this setup work? Am I going to notice a loss of sound quality from having the 4 speakers run off the two outputs (I believe that each put out 100w)? Will the secondary surrounds be distracting to the main listening position? Also, what kind of speaker switch should I be looking for...I figured I would get the one from Radio Shack. Any thoughts or suggestions would be greatly appreciated!!
