I had the pleasure to hear it about 30-35 yrs. ago, and got two MI 9594 horns, and MI 9591 horn to driver adaptors. I use one horn on center speaker system with JBL2482, and mounted above that use JBL2345 I think is the number with Altec 902 at 1.5K Hz, and a couple 075's. Don't play it all that loud, but smaller speakers don't please me that much anymore. When I heard RCA systems, 2 in stereo, 60 watts each, was very impressed.
