I hate on-wall speakers because most of them sound awful. But James Loudspeaker defeated my expectations with the 64CSTOW ($4000/each). Their vertical slit enclosures are made of high-grade aircraft aluminum. There's no center speaker. Instead, the dual two-way design includes two drivers at top, which create a phantom center by summing to mono. The bottom two drivers handle the front left and right channels. Designer Mike Park said he decided to do on-walls because of demand in Europe, where it's inadvisable to poke holes in the walls of historic buildings. The demo featuring Chris Isaak was one of the sonic high points of the show. High-end consumers will want to demo these on-walls. Oh, and that thing in the picture? It's an in-ground sub -- imagine the terror.
