Is that as big as the high end 'stats get? Dang, I thought they were bigger. My SR404 looks to be about 90mm high, but only half that wide, if I am even measuring the right place. Havnt opened them up or anything, I can just see the red ring inside, and figured that was the outer clamp for the stators. No idea though on the other big stats, ESP/950, O2, or HE90.
I am not sure what SR-007's radiating surface area is, but I believe it has a slightly smaller driver.
