I was interested, but then the EP800 announcement happened, and I spent a ton of money with Axiom. Ha ha. It would still be cool to know what the ULS-15 can do, and testing the wireless aspect would be nice.

You could always make whatever subwoofer that you get wireless with the Aperion Home Audio Link™ System. It's a little spendier than I'd like, so here's hoping some competing products come out.
