So, I swapped the original CTS Alnicos of my '73 SR with Eminence Legends 1028K. And wow! The Legends sound like the originals but better. The cone breaks up quite early (as in the originals) but they feel more responsive and alive than the tired 1973 speakers. The old speakers sounded a bit mushy and I have been thinking of replacing them for a long time. Very happy I finally did, highly recommended : ) Anyone out there gone with the Eminence? How about mixing the Alnicos with 1058 ceramics?
