I've been looking to upgrade my speakers in my front room, which is 13' by 14', with an 8 foot ceiling, so a pretty small room. This incredibly precise and detailed diagram will show you the current layout
There is a 7' by 3' window into the kitchen on the left side behind the couch, and the two lines in the bottom left corner represent openings leading to the kitchen and a hallway, and opposite the way into the kitchen is my front door.
Recently I went into a high end Home theater/ audio show room and listened to a 5.1 Klipsch setup consisting of RF 62 II towers, RB 61 rears, RF 62 II center, and a 10" sub. It sounded great, but were a little over my budget, and we were probably 12 - 14' away from the fronts, whereas the chair shown in the diagram, where i would mostly be sitting, is only 8' away from the where I could place speakers. After doing some research, I'm beginning to think that towers would be too much for such dimensions, or at least I wouldn't be able to get their full potential within that distance.
The other considerations are that I am planning to purchase an AVR that outputs 80w per channel, and I will be purchasing a sub, most likely a SVS PB-1000. I don't necessarily need recommendations on speakers, just what would be better for this room. I have Logitech Z-5500 speakers doing the work right now, and they are plenty loud for that room.
