Bedroom system
There are lots of good speaker options in your price range. You might consider putting together a nice 2.1 system with the following:
Bookshelf speakers $4-600/pair
Small Sub (AV123 X-sub?) $200.
Stereo Amp (Behringer A500?) $1-200.
Look for brands like Paradigm, Klipsch, PSB and Energy at a local dealer or check out some of the ID companies like AV123, Ascend, Axiom and SVS.
