Scotty Mac Posted August 29, 2023 Share Posted August 29, 2023 Good day folks, a while back I started a thread in a pair of Cornwall’s (minus woofers) that showed up in my shop. Since then, I have ordered and received the K33e woofers and determined they were a Gen 1 Cornwall but was unable to find a serial number anywhere. I finally started at the Cornwall’s the other day, I decided I was going to give the cabs another coat of Duratech and replace the insulation. So I removed the drivers and When I was pulling out the old blankets I found the original invoice under a blanket and yes, it has the serial numbers, can anyone tell me more about theses particular speakers? also, I noticed I have two different klipsch tweeters, can anyone tell me which is original or “better”…? A friend has a spare square one and would trade for my round one which would give me a matching set but, I would rather the “better” tweeter if there is even a difference? it looks like my mid drivers are different but both the same part number, one has an aftermarket wire connecting it to the XO. Again, any difference, in the two drivers? Unusual to see two different in a set of speakers? Should I seek out another mid? XO look great, plan is just to bench check and if it passes, use as is for now before deciding on which road to go down with regards to tweaks… sound good?

OO1 Posted August 29, 2023 Share Posted August 29, 2023 1984 Cornwall 1 , B3 networks, K-77 tweeter square magnet , K-53 are original , The k-601 plastic horns are not original for 1984 and neither is the k-52H or the k-77 alnico round magnet Quote Link to comment Share on other sites More sharing options...
Marvel Posted August 31, 2023 Share Posted August 31, 2023 The K601 horns and attached drivers are from the beginning of the Cornwall II. The K57-H is the K-52 driver on the K601 plastic horn. At least the left one is. You have quite a mash-up of parts! 1 Quote Link to comment Share on other sites More sharing options...

Could they be Cornwall 1.5, just before the 2 came out. Clearly drivers have been swapped and that’s fine, just trying to determine which drivers, if any, are original? or which drivers I should seek out…?

Bacek Posted August 31, 2023 Share Posted August 31, 2023 I thought all Cornwall I had K55V/K55M squaker. Anyway this is classic version I like the most. So probably this is "1.5" version as upgrading this midrangle horn to one you have makes no sense, so probably it's factory one. Juduging form discussion here B3 was used with newer/smller diaphgram drivers than K55. Round k77 are older. For B3 probably only square was used. So my bet is that K-57K/K-601 and K-77M are your factory set. And this is actually what is on heritage codes page about Cornwall "Mar 1983: The B-3 network and the K-52 midrange driver starts to be used in this model. Component designations were: Woofer Eminence K-33-E, Midrange K-57-K (K-600 Aluminum horn and K-52-K driver with the threaded snout), Tweeter K-77-M and B-3 network." 1 Quote Link to comment Share on other sites More sharing options...

Bacek Posted August 31, 2023 Share Posted August 31, 2023 Aldough is still not proof, I saw industrial Cornwall's from 84 with k57 somewhere on this forum, and another breadcrumb from Klipsch employee On 8/29/2023 at 11:50 PM, OO1 said: K-53 are original There is no K-53 on Scottys picture above but k-57 Quote Link to comment Share on other sites More sharing options...
OO1 Posted August 31, 2023 Share Posted August 31, 2023 the K-57 designation is a combo of a K-600 horn and a K-52H or a K-53 driver with a K-601 Quote Link to comment Share on other sites More sharing options...
Bacek Posted August 31, 2023 Share Posted August 31, 2023 Can you elaborate on this? Does it mean then K-52K + K-600 = K-57K and K-53K + K-601 = K-57K ? Quote Link to comment Share on other sites More sharing options...

I feel you pain. When I bought my La Scalas tweeters where as yours, and woofers where also two different versions and one was partially broken (lousy reconned) Quote Link to comment Share on other sites More sharing options...
