I'm also working on figuring out what characteristics a speaker should have to sound good in a very small room, as I think there's a market for such. The LS-3/5a is sort of the benchmark to be beaten in this regard, and I think it can be beaten soundly by using prosound drivers - assuming a somewhat larger box can be tolerated. This may or may not end up being the same speaker as the stand-mount mentioned above; it depends on what characteristics my investigation highlights.

In the immediate future I'll be working on a fairly large hornspeaker (to make its debut at RMAF) that will have somewhat unorthodox radiation pattern characteristics for a high efficiency design. I'll post details over on my forum after the show - assuming I get 'em done in time.

Finally, if everything else gets built, I want to do a guitar speaker. I've heard a lot of bad-sounding musical instrument speakers, and maybe there are guitarists who would pay a premium for a speaker that made them sound really good.
