@pindac,
I really enjoy my EP speakers (I think they're the 2.8's with 2X 15" Carbon woofers, a 12" Carbon mid and a concentric tweeter, upgraded wiring and stock external crossovers). My only complaint would be the tweeter could be a little smoother, but that's nitpicking, really. Yeah, quite a score.
I listen to mostly classical, hard rock and jazz, and I have no complaints. I do run a Rythmik dual 12" servo sub, too. Overall, the presentation is very good. I would describe the setup as extremely musical.
At this point, I don't think I could go back to a box-type speaker. At least not one I could afford. (BTW, I also own a pair of Tekton Enzo XL's w/ upgraded Beryllium tweeters. Honestly, there's no comparison. 2 entirely different speakers with 2 entirely different presentations.)
OB offers a lot of advantages if you have the room and the patience to dial them in. JM2CW.
