Dogsled Posted July 14 Share Posted July 14 Recently acquired and old Electrovoice version of the Klipschorn using EV woofer 15W, 848HF, and T35 tweeter. It was most likely parts from a Georgian, but I only have the internals. The bass horn is a Klipsch copy or licensed by Klipsch and dates from the early 1950's based on the early T35 version. (also used on Klipsch at that time). I am reworking the system and not sure where to post this? 2 Quote Link to comment Share on other sites More sharing options...
John Warren Posted July 15 Share Posted July 15 A few more photos perhaps. This doesn't look like a factory EV unit. The EV cabinet shop was located in Buchanan, MI. EV cabinet work was excellent, best in the industry and comparable to JBL. EV horns were, if memory serves, all 3/4" thick stock. I don't think they ever sold a "decorator" type unit. 1 Quote Link to comment Share on other sites More sharing options...
grindstone Posted July 15 Share Posted July 15 That's the first style of Georgian utility cabs. If you have ink-stamped ID's on the panels inside, it's either factory kit or factory assembled utility cab. People could buy the finished assembly, the utility cab kit, a completed (empty) utility cab, or just plans. Before 1955, they resembled the (guessing) 2nd/3rd wave (?) of khorns with the full pointy front corners and the side driver access. Throat plates were drawn 5/8 but the rest of the utility cabs were 1/2. +1 that their dress cabs were indeed furniture-quality and thicker. In 1955 & later plans (KD2), driver access is in the front and they started blowing flats across the front corners. After those were released, however, the earlier style was published in a trade magazine. 1 Quote Link to comment Share on other sites More sharing options...

Dogsled Posted July 16 Author Share Posted July 16 (edited) Yes, Have the early crossover as well. The throat was 6 x 13",consistent with the early Klipsch K horns. Do not know about the cabinet history, but these cabinets did not use great plywood. No throat reflectors (i added these), there are visible screw holes on the front which allowed mounting to the decorator Georgian cabinet, and some panels attached with nails, some screws. The panel cuts are precise however, so I suspect this was a factory bass cabinet - these cuts would have been very difficult to get correct in a home shop in the early fifties. Plus this was part of the Georgian speaker as marketed by EV. Also, after checking what dimensions that can be checked, it agrees closely with factory plans -Except for the distance to rear final reflector. That was about 5/8" shy of the factory dimension. Old motor board uses 4 bolts to mount the EV 15W woofer, the woofer has an enormous magnet, parameters are attached. Response of 848HF and T35 on-axis, rel SPL. About 1 m distance. Xover disonnected. Anyway I am repairing this bass cabinet for a stand-alone mono system. The 848HF horn sounds, well, pretty colored. The T35 tweeter is very early version (16ohm) with the diaphragm bonded to the horn - later versions were somewhat different. Very little output above 10KHz. Drivers most likely compromised.
