@snapsc: First, your tweeter question. Where the resister on the tweeter (there is no crossover in the literal sense) kicks in is not divulged by Ohm, and is a matter of some debate. On the old Ohm web site, there was a page that indicated the tweeter only handled 7kHz and up, but others have tried measuring the main drivers and found them rolling off above about 2-3kHz.
As for the quality of the tweeters, Guttenberg has a point. I would say they are adequate. They are not harsh, peak-y or otherwise flawed. Do they have that hard to describe sense of fine detail and filigree one hears on the best speakers? Generally not, although with some really god recordings, they can have that treble magic. I have noticed that the treble on 96/24 needle drops I make do sound subtly but clearly better - cleaner, more refined - than Red Book standard needle drops I make.
Do I wish the tweeter was more refined? Perhaps, although the level of treble refinement did improve when I recently switched my amp. I doubt this could be done without raising prices, though.
Second: If you go with a model not suggested for your room size, you may overdrive them, and possibly damage them. My room size meant I could go with either the 2000s or 3000s. I went with the 2000s, as I already had a good pair of subs (Vandersteen 2Wq), and wished to continue using them. In my room, this combo has worked exceedingly well. I get the huge, tight bass I crave, with the wonderful soundstage and timbre of the Ohms. If you can manage it, and if you’re as much of a bass freak as I am, consider both the appropriate-sized model and a pair of decent subwoofers. I doubt you will be disappointed. 10 years this fall since I got them, and I have no interest in upgrading, at all.
