Anyone ever heard these? They are a 4 way speaker from the 80's. 1" tweet, 5" mid, 8" mid-woofer, and 10" woofer. I have a deal for one really nice pr. and another pr. which needs work. Basically, I can use three of them right off for my mains and center. To me this makes better sense than to use for for mians and surrounds. Wondering if anyone has heard these before?
