I do have an older pair of Focal 3/4" inverted titanium dome, and a pair of Accuton C2-11, 3/4" inverted ceramic tweeters that I planed on trying in the near future. both tweeters are in the 88 to 89 dB sensitivity, so I will have to pad down the mid woofers to match the tweeter levels.

When I get a chance I will give the different tweeters a tray and report back on what I hear.

Actually I am thinking of selling the Ravens, Accutons and Focal tweeters and purchase a pair of high quality ribbons that can be crossed very low say 1500 Hs. Or purchase some of the cheaper plainers to form a true line array
