2) I could be wrong but my ears are telling me that my Heresys have better high frequency extension. There just seems to be a little more "air" there. Bells are clearer, cymbals are crisper, etc.. The Heresys have K-77Ms (square magnet) HF horns and the Cornwalls have K-77 (round alnico? magnets) HF horns. As the Heresys have been relegated to "surround" duty is there any reason to not swap the tweeters? I do plan to install Crites CT125s in both the Heresys and the Cornwalls when budget allows but I'm thinking that swapping them might just satisfy (yea... right) me in the mean time. Thoughts?
For no good reason, a few Cornwalls have passed through my hands. A significant number have had blown tweeters. It is not as easy to hear this awful problem as it might seem. Especially if you have heard Eric Johnson live, without ear protection; especially if you are over 45 years old. But you might just try playing music through the Cornwalls and, using a rolled up magazine or something held to your ear, listen exclusively to the tweeters. If you don't hear the tiz of the cymbals, you have a blown tweeter. Have Mr Crites send you his tweeter diaphragms, too.
Good luck. I love my Cornwalls. You will too.
