VMPS RM 40's. I'm also recently a dealer for them but please accept my opinion as honest. The planar mids with the neo magnets and the ribbon tweeters let all the sound out that's in every pit. In my opinion planars, ribbons and electrostatics just have speed I've not heard from a cone although I've heard people say there are some. Line arrays with ribbon tweeters and many mid/woofs would also be up there. Go listen for yourself.
