I do feel that they are rolled off a bit tho....Maybe just the character of the speaker? Or maybe the newer, thicker diaphragms? I do know that the review of Model 19s from the 70s in one of the audio magazines mentioned that they had a mellow top end with a roll off from 12k on up. So maybe that's what I'm hearing. Any help is greatly appreciated! Thanks
How old are the caps in your networks?

Have you done the ground bypass mod?
