BTW, I subscribe to the camp that says if the speakers sound good for two channel, they will sound good for HT. Outside of the lowest bass (which should be handled by sub(s) anyway) there aren't unique requirements for HT over two channel.

I agree, except for one thing: extreme dynamics. Some people feel that ridiculously efficient speakers are the only thing suitable to be used with home theater. I am not in this camp, as I don't listen at reference levels, and most of the "peaks" are usually in the nether bass regions, which the subwoofer can handle. Crossing over to 80Hz will help even further as far as worrying about those peaks damaging your speakers goes.
If you don't listen to movies at ear bleeding levels, the Salk's are great. If your room isn't utterly gigantic, the Salk's are great. If the name of your game is sheer dynamics, well, there are a only a few brands out there that will deliver, but at the expense of skimping on other important design aspects. I wouldn't ever give up the impressive qualities of my SongTower RT's for more headroom and crazy SPL's. Never!
On the flip side, if I had a dedicated home theater I'd go with something else over the SongTower's and instead use the ST's for 2.x music and multichannel music. My choice for a dedicated HT right now would be the Salk HTS's or Seaton Catalysts. That way I'd have "the best of both worlds."
YMMV
P.S. My comments pertain ONLY to the SongTowers. I am sure the HT2's, V3's and HT3's will fill a large room easily. Oh, and I look forward to your impressions from this weekend's listening session at Dennis' home. Please keep us posted!
