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.

"Fit the battle of Arkansas" is how I heard it.

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.

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.

These are 2 of 20 HBR's shipped to Audio Specialists in Canada on 11/12/1980. Deronda's last name is Beavers.

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.

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.

As I had to post in another thread, too new for the "historian".

Too new for "the historian". Klipsch customer service MIGHT know.

Shipped to Stereo Tronics on 11/12/76 to be exact.

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".

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.

This is a University driver, likely an evolution of the SAHF. I suspect it is University's "last stand" prior to Atlas's K-55-V becoming the standard.

#141 was the 20th K-horn to be built in the Klipsch factory. We consider the prototype as #1, and then there were the 12 Baldwin-built woofers (#2 - #13). An additional 7 (#14 thru #20) were made prior to the factory, which started with #121. So that' why #141 is the 41st K-horn.

#141 assembly began on Aug. 20, 1948. On Nov. 4th it was "filled but not stained or lacquered". It was crated and shipped Nov. 8, 1948 to Feulner (?), and was a "Style 6" (curved HF section). [Style 7 was when it basically took on the current cosmetics. On March, 28, 1949, PWK released a sketch (sneak preview) of Style 7.] No drivers were called out, so I expect it left the factory with none. I also suspect the HF horn may have been replaced when it was upgraded to a 3-way, including the K-500/5000 crossover pictured. The Museum has #151, and it shipped with a Stephens P-15 HF. Aside from the original prototype and Baldwin #13, this is the oldest Klipsch-built K-horn I know of. Congratulations!

You have "starter" Heresy's ("B" designation). #538 shipped Feb. 22, 1963, and #585 shipped June 10, 1963. "B's" were intended to be upgraded eventually to full 3-ways. They shipped with a K-22 woofer that incorporated a whizzer cone to achieve some amount of high frequencies. I suspect the tweeter and mid holes are covered with a paperboard cover from the inside. If it's any comfort, they are fairly rare!

Sometimes they ran out of red ink!

Bob N could be Bob Noble, a former employee that may have gotten a "special deal"!

I believe this is the referenced Dope from Hope. Wish I had an original, but fortunately it was reprinted!

I concur!

Hi Greg, The standard Shorthorn (Model S) started with serial # 501 on Jan. 25, 1956. No idea why that starting point. Last one was 1E166 shipped Dec. 13, 1968. That looks like 666 in total, and a number PWK would have found amusing! The Shorthorn Model T (for television monitor) was much rarer. Two "experimental" units in 1955 and 1956, with 46 "regular" units between Nov. 8, 1956 and Aug. 7, 1962. Total of 48. I would agree that cannibalization would be unfortunate! Jim

The aspect ratio looks appropriate for Cornwall's. Of course, PWK would have crapped to see the un-toed-in arrangement! I have heard (unofficially) that Sinatra had K-horns.

Prior to the Belle, PWK used a WALNUT LaScala as a center. I have it.

28W186 shipped to Canada on 6/22/81. 29X610 shipped to AAFES (overseas military) on 6/28/82. Both as LSBR's.

It could have used a separate mono amp, but many of the tube amps of the day could be "jury-rigged" to provide a summed channel.
