Wellfed, I would love to find out sometime, though I've never been a fan of added rear firing tweeters (who knows, at this quality level, maybe they're great and they certainly do get some good reviews). I have not yet heard the VR-11's. Of course, I'm not sure I can afford the VR-11's either ;-) Cost aside, I would be hard pressed to part with my WAS's. I've owned Montana's now for about 4 years and truly enjoy them. The speakers and cross-overs are very well matched so the music just flows evenly across the spectrum and, I believe, presents a very fine mix/match of detail and musicality.
