If you want a good system for music I'd go with the Fluance sx-htb and a referb Harman Kardon avr125 for $179 free shipping at ecost.com
The dayton sub at partsexpress is a good choice.
That setup will put you on budget between $500 and $600. I have all this equipment at home and I listen to music more than I watch films.
I doubt you could get a system like that from your local retailers with a limited budget.
If you want only bookshelf sized speakers that could be more of a problem for music with this budget. There's the JBL nsp1II set but I doubt they're as good for music as the sx-htb set are.
There's also the Onkyo sks-ht500 speaker set but that comes with a sub that some people find weak. If you're talking about how you want more bass? Well......

I also saw good reviews with the HC6 Accoustic Research speakers and sub. There's no brackets to mount them on walls and they are ported so you'll have to mount them on stands. I've seen them on the internet for $400.
