scottwissing you got an incredible deal! lkp1952 is correct. Those are Beryl speakers. And you are correct, they were made by Dale Pitcher when he was in Lincoln. They were made in the early 1990's and sold for anywhere between $2000 to $5000 a pair depending on the deal you got from Dale. I have a pair myself down in the basement in my backup system. My entire main 2 channel system is made by Dale: preamp, amps, external crossovers, speakers, interconnects, and speaker cables. He made incredible stuff. Unfortunately he went off the deep end about 6 years ago with a psychotic break and of course is out of business. Such a shame, he was truly an electronic genius.
A salesman who sold a lot of Dale's stuff is Duane Randleman, now with Automated Lifestyles in Bettendorf, Iowa. He would know details about those speakers if you need more info.
