  1. It changed on November 20, 1987. The molded horn is "foamed" ABS which results in a more damped structure with a just barely measurable decrease in harmonic distortion.
  2. The listening position was very near the yellow t-shirt, with the 3-channel array on the opposite long wall. PWK was adamant about using the long wall when possible. With a derived center channel the width of the listening area is maximized.
  3. 116 refers to Building 116 of the WWII Southwest Proving Ground. It was the telephone exchange that Paul bought after the war to become the first factory. It is now the Klipsch Museum of Audio History. "The Studio" was Paul's listening room, as well as where he recorded some of the Klipschtapes. The Masonite appears to have been bent and stapled over semi-circular gussets, and was painted along with the rest of the walls. Sizes vary from 8' long by 3 1/2' tall by 12" deep for the largest, to 2 1/2' wide by 3 1/2' tall by 8" deep for the smallest.
  4. "Fit the battle of Arkansas" is how I heard it.
  5. Deciphering the first logbook is not as simple as one would imagine. #166 is listed as Style 6 and shipped 5/26/1949. #167 is listed as Style 7 and shipped 11/23/1949. In between these dates at least seven other Khorns were shipped with serial numbers both lower and higher than these, and without styles mentioned.
  6. The Chorus followed the introduction of the Forte, and was designed by Kerry Geist. It ultimately "replaced" the Cornwall for some years until the Cornwall was "brought back due to popular demand". The names at that time were, and still are, heavily influenced by the Marketing department. Musical references seemed appropriate.

    1980 Heresy

    These are 2 of 20 HBR's shipped to Audio Specialists in Canada on 11/12/1980. Deronda's last name is Beavers.
  8. The single box LaScala was discontinued when the AL5 two-piece version was introduced in 2006. I have no access to serial numbers after the hand-written logbooks were replaced with computer systems in about 1983. These systems changed many times. Whether the documentation exists currently would be a Klipsch Group, Inc. (KGI) question. There is the "CODEX" which has resided on the Forum for many years. It is attached. To be clear, I worked until 2016 for KGI. I now work for the Klipsch Heritage Museum Association, Inc., a distinct non-profit organization, and not a part of KGI.

  9. The woofer is date coded the 32nd week of 1980. The tweeters have an "R" stamped, indicating they were replaced at some time. They were built by Electro-Voice. If the capacitors are not leaking oil, they are very likely just fine. Everything seems to be in order.
  10. As I had to post in another thread, too new for the "historian".
  11. Too new for "the historian". Klipsch customer service MIGHT know.
  12. Shipped to Stereo Tronics on 11/12/76 to be exact.
  13. 2H963 shipped Sept. 2, 1970. It is possible when the K-700 horn came into use in 1966 , that the model MAY have been unofficially referred to as a "Heresy II".
  14. Magnavox is very likely the original woofer. khorn51's unit is undoubtedly "one of the seven" built after the Baldwin's, and prior to #121 being built in the basement of what is now the Museum. We have #18 and #20 here. That would suggest it is #14-#17, or #19. I would love to have more info on this unit. The August 47 demo was Armstrong's second one using a Khorn. His prior demo used a "Khorn" built by a Bell Labs engineer and friend of PWK.
