bsacco1 Posted January 6, 2023 Share Posted January 6, 2023 I own a pair of 80s Cornwalls. I was wondering if it made any difference in sound if you changed the woofers from k-33s to K-43s? I mean, are the original crossovers designed for ONLY K-33s? Or does it not make any difference if you put K-43s in? Quote Link to comment Share on other sites More sharing options...

Those woofers are interchangeable in the La Scala so I imagine they should be in the Cornwall as well probably lose a bit of low end in exchange for better mid bass? If you have the woofers already wouldn't hurt to swap them out and give it a try maybe report back your impressions? 1 Quote Link to comment Share on other sites More sharing options...
Marvel Posted January 6, 2023 Share Posted January 6, 2023 The polar response of the two woofers may not be the same, which may not be a problem when used in a horn, but could really make a difference when used in a direct radiator cabinet when it gets to the the crossover point. I'm sure that the Chief would know. 1 Quote Link to comment Share on other sites More sharing options...
bsacco1 Posted January 6, 2023 Author Share Posted January 6, 2023 Here is something I do know...the K-43 have a much larger magnet than the K-33s. I have no idea what you mean by the term " direct radiator cabinet" or "polar response" ... these are technical terms that are out of my league. I just know simple stuff like does it sound better or not. Quote Link to comment Share on other sites More sharing options...
Marvel Posted January 6, 2023 Share Posted January 6, 2023 1 hour ago, bsacco1 said: I have no idea what you mean... A given direct radiator doesn't have the same horizontal/vertical output through its whole frequency range. If the horizontal response at the crossover (700Hz) point doesn't match the mid horn/driver, it probably won't sound correct. That's one of the reasons the crossover point for the drivers is chosen, so they will match. So the question is: Are the K33 and K-43 the same in that regard? Probably not, and the sensitivity is certainly different at different frequencies. 1 Quote Link to comment Share on other sites More sharing options...

If three people tell you it sounds better and three people tell you it doesn't, how do you decide what to do? 1 Quote Link to comment Share on other sites More sharing options...

Deang Posted January 6, 2023 Share Posted January 6, 2023 Definitely don’t go with the guy using words you don’t understand. I’m really spun up this week. A solid three days on the Klipsch pages on Facebook has me pretty much fried. 1 Quote Link to comment Share on other sites More sharing options...
