K-77K

[kg4guy]

Anyone know the specification on the K-77-K tweeter for the klipsch heresy series 1

[Guest " "]

how about a picture of the k-77-k

To my knowledge the Heresy only used the K-77 (alnico round magnet) and the K-77M (square ceramic magnet)

Are you reading the final "K" off of the tweeter itself, or off of something else (paper documentation)?

In following this since the '60s, I haven't heard of a K-77K until now.

I thought the first tweeter used in Heresy, LaScala, Cornwall, and the Klipschorn (when it first went "three way") was the K-77 with no other marks (in reality, the best testing EV T-35s from a larger group of T-35s, selected and separated into matched pairs, and marked, as part of a deal with EV, "K-77"). Then came the K-77M, and starting in the 21st century, for those speakers (Klipschorn and LaScala II) still using a 77 (for its efficiency and signature sound?) the K-77F.

I still don't know, and would like to know, what the K-77D is that is in the limited edition 60th Anniversary Klipschorns -- I suspect that it is a highly selected F.... anybody know?

the "D" is from a different vendor than the F (and before you ask, I don't know the vendor, nor could I tell)

K-77 ...the "K" was added from time to time do to the use of "K" numbers...k-33-k , k-1001-k, ect
