Have you made or considered making anything with the BG R40,50,75? :> http://www.parts-express.com/wizards/searchResults.cfm?srchExt=Mfg&srchMfg=275
They look perfect for a line array but everything I've seen about them seems pretty old

I've not been using them mainly because their sensitivity is too low for line arrays. The RAAL /Fountek ribbons also have better top octave extension and dispersion.
