Been giving this some thought, and thanks to those who have offered suggestions. Here's is what I'm thinking of doing for my new audio system. I want to put four JBL E10's for the side and rear surrounds, three E50's for the left and right mains and center channel, and an SVS sub. All this connected to a pioneer VSX1014. I could get an EC35 for the center, but I like the imaging from three identical speakers up front, and since the E50's come in pairs, I can use the extra as either a spare or in another room. I really don't think I need anything bigger than E50's for mains. This room is 11 x 20 feet, so it's not huge by any means, 1650 cubic feet total. I have a projection screen that is as wide as the room, so a tall speaker, like an E80 would end up being in front of the screen, so I chose an E50 because of it's horizontal configuration. So that's the plan, please comment good or bad or any suggestions, I'd appreciate any and all comments. Just understand the speakers will be JBL regardless due to price, value, style, sound and I've had them in the past and was able to drive the heck out of them without any problems.
