The A-shaped Avalon Aspect boasts 92dB efficiency, which should make it compatible with home theater use as long as you're willing to buy five of them -- no complementary center or other models yet. For $8500/pair you get two 7-inch kevlar woofers and a one-inch proprietary neodymium composite tweeter. The latter gets a waveguide-like treatment thanks to a foam structure built into grille. You won't see it unless you pop the grille and look at the underside, as Avalon showed us.
