Hi all, I did some searching and found really nothing on these speakers used in OB, but the T/S looked good for OB and efficiency was good. I am thinking of using two tens and one tweet per baffle (D'appolito style) with a 12" JBL GT in a sealed box; Qtc of .6 - .7. I think a two way L-R 3 KHz xover would be good, but I'm just guessing. To those with experience with these speakers or if you see a hole in my logic, please give me a nudge. Thanks much, Brad
