CraigSUB VS-18.1 subwoofer + Dayton Amp: $1240 shipped

Just slightly over budget. This would easily be the most powerful system, but the thing is accommodating the center might be a problem depending on your display setup, and the sub is pretty scary looking. This setup would get you closest to commercial theater dynamics.
Remember you also have to buy accessories like cabling and mounts, if you don't have them already. Get your speaker cable and HDMI cable at monoprice.com (save your money, do not buy them at a retail store!), and the bookshelf speakers mounts you will want are the
AM40 Pinpoint side-clamping mounts
. Seriously, if you need mounts, get those, they will save you a big headache.
