can any body tell me what would be a good set of speakers for my living room? the dimensions of the room are 16' from the front wall (which is where the tv sits) to the rear wall. my couch is 10' from the tv. the room is 14' wide. i am thinking about the VF-36 which is in my approxamate price range, but i dont want to pay for a larger set of speakers then i need. should i go with something larger like the WF-34, or smaller like the VF-35? im looking for the complete home theater system with front, center, rear, and sub. can anybody give me advice?
