You are getting some pretty good suggestions here, and I especially like the JBL Studio suggestions. One tower that you might try is the
HECO Aurora 1000s - pretty good deal especially when on sale. Throw in a couple of
BIC PL-300 subs to supplement the low end. Another high-value system I think might be really good for your circumstances is a pair of
Hsu CCB-8s on top of some
Polk HTS-12 subwoofers. That would be punchy and image very well. Another great sub/bookshelf pairing would be the
Monoprice Monolith THX-365s on some
Hsu VTF-2 mk5s. There are a lot of ways you could go here that would be great, and these are just a few suggestions.
