Cornwall Thoughts

Those Cornwalls shouldn't have the square magnet K-77-M's. Those Cornwalls are 1977 models and would have had the round magnet Alnico K-77 tweeters installed originally. The square magnet K-77-M's didn't come out until 1980. In other words, the tweeters have been replaced if they actually are the K-77-M's. Perhaps the original tweeters were blown, which may indicate hard use (abuse), but perhaps they were simply updated.

The K-77-M tweeters are 2-3 dB louder than the K-77's. The Type "E" crossovers were designed for the K-77 and don't take into account the louder volume of the newer tweeter.

Don't be surprised if those Cornwalls sound a bit harsh because of the louder tweeter, if, in fact, the K-77-M's are actually installed.

Hardhead,

It think the guy just copied the Klipsch blurb on the Cornwall. They likely have the alnico K-77s if they are from 1977.

Also, they should have type B crossovers not type E. But, discussing the type E for the Heresy, Klipsch did not change the crossover's tweeter section at all when the change from K-77 alnico to K-77M occured.

Agree with Bob. I also think he just did a "cut and paste" of the Klipsch specs. Even if he did swap the tweeters, you COULD swap them/trade if necessary (doubt he did, though). If the drivers all work, this is a BUY price....and when factoring in local availability, it is as good of situation as can be if you are in the market for Cornwalls. Shipping these is a PAIN - and it's risky.

Have you bought them yet? Do you plan to? If you not planning on buying, maybe another forum member would.

Check to see if they still are available.
