I just scored a pair of Holosonic 1's for nothing last night and i was wondering if anyone knows anything about them? They were bought in 1978 and the girls father i got them from was the original owner. I hooked them up last night and they sound really good. occasionally i am hearing on one speaker some tweeter distortion but I have yet to figure out which one. I have googled the #$@@$ out it and cant find very much at all. They appear to be in pretty good shape.
