Ozzy62: Actually, the overall dimensions of my basement room are 26 X 20 X 6 (low ceiling), but the area best suited for the front wall is an alcove about 10' wide. Considering I need the front mains to clear a RPTV screen (I know, but that's what I have to work with), speaker width is critical. The 1Cs are fairly far out into the room, and I would like to place their successors far out into the room as well.
Jkalman: It's just you. Vandersteen designs are somewhat unique, and like planars or other unusual designs, they have a strong following. Besides, since I basically asked for brand suggestions other than Vandersteen, I can hardly be called a shill. Proper etiquette on this board is to post to existing threads rather than start new ones when possible, IIRC.
