Bookshelf speakers for a small room
I'm looking to upgrade my speaker system, which is currently a JVC 5.1 system with 3" woofers and no tweeters at all in the satellites. The room is fairly small, about 11x14 (open to a kitchen/dining area, 11x27 overall). As you can see from the photos, the area available for front speakers is limited by the door and the HVAC unit. There's about 28 cm/11" of space on either side of the TV. So what I'm looking for is something compact in the $600-700 range.
For pretty much any centre speaker there's no room in front of the TV - the stand doesn't have room either on top or inside. There's also not enough room for speaker stands on either side of the setup. I'd like to mount the TV on the wall, which would free up space on the TV stand, but I rent so I don't know if I can do that - it's something I'm looking into. Another option would be to get a new stand that would accommodate a centre channel better. Suggestions on how everything is arranged would be welcome.
I've read rave reviews about the Pioneer SP-BS22-LR and its matching speakers, and I could get the whole 5.1 system for under $600. But they seem quite bulky, especially if two of them are used as surrounds. I'm in Canada, and right now Future Shop has a good deal on Energy CB10 bookshelf speakers. They're more compact than the Pioneers and have bigger drivers. I can get them for $180/pair compared to $140 for the Pioneers. Any other ideas? I'm happy to buy second hand speakers if that would get me better value.
Finally, is the quality of the surround speakers as important as the main speakers? For those speakers the smaller the better.
