I've never heard them, but they seem a bit pricey compaired to what you get with an Axiom system.
Aperion surrounds are the same as their front bookshelf speakers, not even bi- or di-polar. They have 1 tower, 1 bookshelf, 2 centers (one of which is just another of their front bookshelfs put on it's side), and a couple of smaller subs. The most interesting thing about them is that they offer front towers with built in powered 8" woofers built in. I know that my wife's biggest gripe with the system I want is that I plan on having a SVS PCi20-39 cylinder sub, and she saw these speakers at a local home theater shop that had the powered wooder (granted they were dual 12" powered woofers in EACH front) and they didn't have a seperate sub. Of course, those were also about $5000 for a 5 speaker setup.
