For volume and lots of bass, Aerial would probably be a good choice. I've seen several HT systems with them and they play very loud and clean.
For better sound quality and not so much volume, a pair of Vandersteen 3's and the matching subs would be very hard to beat. You would also have a lot more setup options with them. The 3's are very neutral but you can move either way depending on equipment and setup. You'll come in way under budget as well.
