Questions come up occasionally regarding the K-77. It is a rebranded EV T-35 which passed strict Klipsch QC. According to an article, PWK selected the EV after EV adopted the Avedon phase plug. It was first used in a K-Horn in October 1959. University eventually acquired EV and published a spec sheet which is more elaborate than what EV published. My read is that horizontal coverage is greater when the unit is oriented with the long axis vertical -- i.e. that the patterns shown were obtained with the unit oriented as shown in the picture. Per the timeline for K-Horns: The first three-way Klipschorn incorporated a Jensen RP203 tweeter. This tweeter came from the famous Jensen G-610 Triaxial 15" driver and required considerable negotiations with Jensen. It was not until mid-1952 that all Klipschorns were three-way. A two-way Klipschorn with response to 12Khz was generally adequate for program material up to that time. The University MID-T- 4401 replaced the Jensen unit as the tweeter of choice later in 1951.
