Troy:

I mused about that type of a speaker some time ago. When I visited the factory a couple of years ago I spied an 'experimental' speaker - 3-way I think - that had the EP400 8" driver. I don't know if it was powered or not.

Powered tower designs don't seem to be too popular for some reason; however I would love to have an M2 + powered EP400 in the same tower in HG Rosewood, ha!!...
