If I am not mistaken the Icon V series was actually designed by Klipsch specifically for Best Buy. I don't think any other dealer sales them. Its even been mentioned that Best Buy had some input as to the design (customers wanting thin, not too obtrusive and blends well with most decore, easy to drive with most average lower powered receivers, good price value
(cheaper)).
The mid/woofer drivers are cheaper in most respects. They are a paper or poly type cone. Aluminum driver in the horn tweeter. The Cabinets are actually well put together, probably better than the Synergy Series. The crossovers are about as cheap as can be.
I personally have listened to the quiet a bit, and I don't really like them. They seem to me like they are missing something. "Slam" is the only thing I can think to call it. The mids don't seem to keep up with the tweeters. And to my ears, the center doesn't match well tonally with either of the two tower models, especially the VF-36. If I had these speakers I would do the center, bookshelf, and surrounds, and forget about the towers. But thats just me.
