wuzzzer Posted May 10, 2019 Share Posted May 10, 2019 My 1983 Heresy have the soldered lug dual phase plug K-55-V drivers and I absolutely love them. If I ever came across a pair of Cornwalls, Khorns, LaScala etc from that era would that midrange driver be a direct swap or would anything in the networks or horns themselves need to be modified? I don't have anything on my radar but just wanted to plan in case anything ever pops up. Quote Link to comment Share on other sites More sharing options...

PWK was able to save lots of money on the drivers he used due to that "commonality" of parts and volume purchases of them! Many consider that as a good part of his "genius" in designing his speakers! By using the same compression driver for the mid-range in his speakers it only required different horn lenses to be attached to them! 2 Quote Link to comment Share on other sites More sharing options...
