Thought I'd go ahead and post some info on the Rectilinear 5 as there is very little trace of them at this point. I've had a pair since about 1979 and still think they look and sound great. 12" woofer (with yellow surround foam!), 6" midrange, two tweeters. Foam just failed this year (the speakers were already a couple of years old when I got them!). Anyone else remember them?
