How will you do a Fluance Signature as a center with a TV? I could see that happening with an acoustically transparent projection screen, but not a TV. That is a tall speaker. Obviously you would have to contact Fluance to arrange the separate purchase of a single speaker. If you could somehow swing three Signature towers for a front stage setup, that would be pretty good front stage.
As for the Hsu speakers, I think CCB-8s would make for a great front stage but overkill for surrounds. If you went with Hsu, I would consider going with the HB-1s for surrounds, they are very capable speakers themselves, and would be easier to mount. Although it certainly doesn't hurt to have CCB-8s for surround speakers. By the way, the Hsu package you would want more to be looking at is the
Hybrid 15h CCB-8 package, not just the speaker package, you get more of a discount. If I were looking at Hsu, I would go for three CCB-s for the front stage, four HB-1s for surrounds, and two VTF15h subs, and ask Hsu what kind of discount they can give you for a package like that. Get it all done at once for maximum discount.
As for SVS, I don't know if that are any better than the Hsu, Ascend, or Fluance speakers. I certainly would not presume that their higher price means they are better, although I am sure they are competent speakers. But these are all very competent speakers. I am sure a significant portion of the cost is for the piano black finish. They do look quite nice. For SVS, if it is possible, I would swing for an Ultra bookshelf for the center rather than the Ultra center. That would reduce cost but probably not sacrifice any performance.
May I ask what kind of room will this equipment be going in? A dedicated media room like a home theater room? How large is the room and what are the dimensions?
