I am looking to setup a home theater in a fairly large room soemthing like 15x20. The problem is there is no back wall the area behind the listening area opens into a kitchen/dinning area. Also the T.V due to a fire place is located pretty much in the right corner of the room. I have been doing research and have narrowed the satelittes down to either the bic dv62si or the klipsch rb-35 I think. I haven't picked out a center yet and already have a reciever.I am also looking to get a decent sub but am willing to sacrifice sub quality for better spekers. I am looking to try and stay under $600. Any suggestions on speakers would be welcome and I really could use some help on how to setup the speakers based on the unusual way the room is setup.

Thanks,
