I have a pair of HE 10.1's that I use with a 2 channel system. I'm very pleased with the way they sound. So pleased that I'm toying with the idea of building another pair to use as surrounds and figuring out something to use for a center. I'd love to be able to listen to multi-channel DVD-A's with these guys. The entertainment center that houses the RPTV and all of the equipment simply won't allow for another 10.1 as a center. There is a bit under 11" available height between the TV and the shelf above it. An email from Adire a few months ago indicated that they were working on a 8.1 configuration but I haven't seen any new information since. On a different but related subject. Shielding? Is an unshielded center sitting on top of a RPTV far enough away from the tubes to not cause problems. If I do end up trying to design something like a 8.1 for a center shielding it could well be an issue.
