I just got some JTR Triple 12 speakers and am blown away by them. Now granted I've only had them hooked up for a day now lol, and only have the front 3 (LCR), but they are incredible.
I have heard Klipsch RF7's, B&W CM9's, Salk SongTowers, Golden Ear's, and Paradigm speakers (all in the same range you are looking at spending) and these blow them out of the water.
I found the JTR's in your range used, but brand new they will be over budget. But the Triple 8's are supposed to be great as well, but I just decided if I'm going to spend that money for new Triple 8's, why not get the Triple 12's used for near the same price?
Now granted I've only watched like 2 hours of movie clips so far, but my basement sounds like, if not better, than an actual movie theater, and this is without the surrounds hooked up. I'm much more of a movie person than music though, so i haven't heard how music sounds on these yet other than some club/house types of songs, which sounded great.
I went to sleep last night with a grin on my face and had one for 2 hours straight while watching various movie clips from the Reference Demo discs.
