The third one looms the closet.

If that's the case, you might be better off buying active powered PA speakers. Most home theater speakers aren't going to be able to handle the volume you're probably going to throw at them. You won't have to buy a receiver either, because these speakers have their own power source.

These speakers would be good, and you'd need a mixer like this (and power supply to hook your source up to, using this cable.

We had a system similar to this in our frat house in college, and those speakers were just about indestructible and ridiculously loud. You can also add a subwoofer (or two) if you want.

Edit: Forgot about speaker cables.

You can also skip the mixer and just directly hook up your audio source to the speakers using this.
