well - these are about 3 years in the making (took me that long to source at least 16 of the full range drivers). A brief overview:
Open Baffle Line Arrays using KLH 4.5 inch fullrange speakers; current incarnation uses a radio shack dual radial horn tweeter (97 db eff.) for the top end, and some old KLH model 6's for the low end (corner loaded so to speak). Crossover is still in the works, but right out of the gate these things are DYNAMIC. About two weeks ago I cleaned the rug in our sunroom, and before anythign wen back in, I set up just the speakers and the audio system to see what they'd do . . .
they sound MUCH better about 4- 5 feet from the back wall, and with no furniture in the room
BUT - even in their 'compromised' current setup, I'm very pleased thus far. It really is hard to beat the transients and 'liveliness' of OB . . . add the large soundstage of a line array, and I think I'm zeroing in on my nirvana . . .
downsides: bloated bass, 'weird' interface with the tweeter . . . all to be solved by crossover work, and/or active crossover / triamping . . . aaaaaaand maybe a 15" driver woofer array for bass
