Frzninvt Posted July 1, 2004 Share Posted July 1, 2004 1984 I believe was the transition point to the AK crossover network, I think they were still using the K-55V but they may have K-55M midranges in them. They should still have the metal K-400 horns, the K-77M square magnet tweeters. If you are compelled to open the woofer trap doors on the side they should have the K-33E woofers in them. If any drivers have an "R" stamped on them that means that they have been replaced with a refurbished one from Klipsch. Good luck, I am certain that you will be happy. The parts for them are still readily available. Welcome to the forum. Quote Link to comment Share on other sites More sharing options...
lynnm Posted July 1, 2004 Share Posted July 1, 2004 I wouldn't sweat the driver complement too much. I would want to focus on how they sound. Quote Link to comment Share on other sites More sharing options...

I noticed the "R" stamped on the K55M drivers so I called Ginney who handled the parts questions at Klipsch at that time(Great Person and would go out of her way to help you like every one I ever talked to at Klipsch) and she told me the "R" meant that the driver was a replacement part and those carried less waranty than the orginal drivers but they are "New Parts" not rebuilt. mike Quote Link to comment Share on other sites More sharing options...
