I'm buying a 5.1 system. I'll mainly use it for home theatre. It will be in my family room, which has 10 foot ceilings. It's probably 12 feet deep and 23 feet long (it opens into a kitchen and breakfast area). I'm planning on the Yamaha RX-V1300 receiver ($600). I'm leaning towards an HSU or SVS box subwoofer ($500-$600). I'd like to keep my total costs under $2000, which gives me about $800 to play with. Several questions:

1. Am I insane in allocating my money this way? Should I decrease my subwoofer investment in favor of improving the remaining speakers?

2. If not, what brands would people recommend for the other five speakers? I'm somewhat interested in BIC or JBL right now, but don't know if they're a good fit, given my other needs.
