I acquired a new to me pair of KLH Model 6's. The cabinets are in very good condition as well as the grills. I got them home and hooked them up to the Mac 1700. I immediately noticed a slight rattle in one of them. I then located the problem immediately. A loose tweeter...which led me to find out that 3 of the 4 screws were stripped out in the wood. I then removed the tweeter and immediately recognized that the magnet was not square and said made in Japan on the back. Well I was a little disappointed that it was not original. Question these tweeters have a metal grill and say 30w on the back. I would like to find some original ones to replace these. Does anyone have the actual part #? I know that KLH made many similar speakers during this time period, and I was wondering if they used the same model tweeters which could be interchangeable . I am still new to this vintage stuff and am learning so thanks for the patience.
