I've got a WE 26a Horn. I really want to hear it play, but I'm not gonna be able to get a 594a driver (that it was designed for) anytime soon. I might be able to get a 555. If I got an adaptor for a 555 would this work? I think the 555 is 1" while the 594a is 2". Otherwise can anyone suggest any other compression drivers that would also work with this horn (JBL, Altec ,TAD?)
He had a pair of JBL 375s connected to a WE 26A horn via a WE 22B dual throat adapter. The drivers and horn sat on top of a JBL C55 "scoop" cabinet with dual JBL 140-R woofers.
I know this because I acquired this speaker from his estate.
You forgot to mention how it sounded.
Good question! Regrettably, I never got to hear it. It was too big to bring down into my basement listening room. Also, a friend wanted the 375s for a project, so that was that.
Eventually, I brought an amp and source upstairs to listen to the woofer section only. It, along with an early EV Patrician that I acquired, reproduced the most impressive bass I have heard from any speakers.
Thanks Gerry, fascinating. Do you know what he used for crossover and amplification? I'll be using my jbl 4343's for the low end in my rig. Ive just got the single driver 22a throat. the jbl 375 could be a good option as it has the 4 mounting holes.
The crossover was a JBL N500. The best amp he had in the house (note that this was he weekend home in Connecticut), was a Fisher SA-1000. It may have been hooked up to it, I don't remember.
Almost as interesting as the speaker itself was a two-page letter from the president of JBL, William H. Thomas, to Mr. Fisher. In the letter, which is dated February 23, 1970, Mr. Thomas writes about the system being assembled and tested.
Noted studio design expert and JBL Technical Service Manager George Augspurger was mentioned in the letter and apparently was in charge of overseeing this order from Mr. Fisher. I still have the letter.
Very Interesting Gerry. So this was a mono system? So you still have the horn and the woofer rig? that crosocer looks to be huge. the fisher amp looks pretty sweet too. Must have sounded amazing, not a bad second setup for the weekend house.
on the hunt for a jbl 375 now.
you can just as well use JBL 2441 instead of JBL 375 at a fraction of cost for the latter.
Good suggestion. There's also an upgrade path w the JBL's (including other JBL options here depending on 16 or 8ohm). And that's an aftermarket Beryllium Diaphragm.
The Klipsch K55 was based on the WE555. It even uses the same threads if I remember properly. I've seen them on WE horns. I tried to find a pic I had of K55s on a WE16 but just too many image on PC. Anyway this would be a cheap way to listen to them.
High sensitivity, wide dynamic range, low distortion, and smooth frequency response. Pwk
The Renkus-Heinz SSD3301 2" exit, 4 bolt (fits JBL large format) sound quite nice, still easy to find, affordable and has an Altec heritage. I just don't know if the 4 bolt pattern is the same as the WE594A.
As I understand it the bolt circle diameter of 594A and 375 are slightly different. A talented machinist to make an adapter is called for here, not a file!
The Wente experimental driver from the Bell Labs Fletcher horn system (later commercialized as the 594A) used a 4" diaphragm, but had a threaded 1.5" exit format identical to that used by Lansing and RCA in the mid to late 1930s. So in view of this history a number of drivers might be seen as appropriate for the 26A horn.
I would start with an Altec 288 variant and appropriate adapter and go from there.
Finding the optimum room is going to be a challenge.
Thanks Guys, both good suggestions. I think I may need to make an adapter. I think I can do this ok. I can CAD one up and get it sandcast in Aluminium probably.
Yes my room is not ideal, I suspect the best room for this horn is a 1000 seat theater ha.
