JBL made both large and small format compression drivers for RCA in the late 1960s and 1970s. I think they were basically 175s and 375s, but had different back covers and were painted a dark "Midnight blue."

Wow, I had a Janis SW-1, thought it was terrible. I remember having to take the bottom off the cabinet to repair some flood damage, and the driver was some cheap-framed 15". Maybe someone was in there before I got it & swapped speakers.Originally Posted by Don McRitchie
The x-over/amp from that Janis combo (Interphase A?) is heading for e-bay any day now, if anyone's interested in it.

I don't see the 5A540 in there, I have a pair of working ones on 2345 horns. Came with cracked D16R2420 dias, figured a pair of aftermarket titaniums was called for...Originally Posted by Robh3606

Drive 'em to the Xmax!
Not to be nit picky here, but the drivers labeled like this were actually made by Ampex under license from JBL. They made several drivers and at least the large potato mashers for theater systems.

Hi,
add the K 130 to the list which was made for Peavey guitar cabs. It might as well be a D 130. Im not sure about that.
I have one of these with a Peavy decal and believe this to be pretty rare.
Maybe I can post a pic if anyone is interested.
It seems JBL did OEM products for very reasonable prices at that time.
BTW I wanna thank Steve Shell for his profound and knowledgeable postings !! He´s a wealth of good information for all of us. Thanks !
greets
Franz
AND add the D140 for Peavey too.Originally Posted by franz

the kustom sidewinder tuck and roll guitar amp uses a d130f.
The big,portable Leslie organ speaker,925, I believe, also used a branded 140 for the bottom and 2440 for the top...
Although Zingali speakers used JBL drivers in the past, and pictures of past products using JBL 2234/5H woofers can be found with a google image search, the current products use B&C drivers, 15TBX100, 12TBX100, and DE500 compression drivers. If I had to guess at the manufacturer of the drivers in the smaller models I would guess Ciare since they produce a lot of OEM drivers.

Spotted in an ebay auction, a bubbleback 375 labeled as "James B Lansing Model HFH-2b Impedance 16 ohms Specially Designed for High-Fidelity House". The name plate is the same engraved black/white plastic laminate as used on the first 3000-4000 375s made. Included in the auction is an associated 075 with a the serial number 22880. The plastic nameplate and 075 serial number would seem to date this to sometime around the late 50's or very early 60's.
Does anyone know about High-Fidelity House?

Glen, I believe that High Fidelity House was a hi fi dealer in Pasadena, CA in the 1950s. I saw some of their literature on ebay just recently.
Those Westrex 375s may have been among the first built. As John Eargle has told us the story, Mr. John Frayne of Westrex Corporation visited JBL President William Thomas in the early 1950s. He was toting a Western Electric 594A field coil 4" diaphragm compression driver, built in the late 1930s. He asked Thomas if JBL could build a permanent magnet version of this driver for the Westrex sound systems built for export. Thomas leaned out his office door and said "Bart, could you come here a minute?" Bart Locanthi entered the office, was told of the request and said "Yes, I think so." Production of the 375 commenced soon after.
Ampex also used 375s in their theatre systems when they became available, and JBL began using them in the Hartsfield in 1954.
Thanks for the tip, search turned up another connection, in 1975 Harman-Kardon sued B&O AND High Fidelity House for patent infringement over linear tracking turntables, settled in 1976 when B&O bought the patents from H-K:

Apparently in the mid to late 70's Harman Kardon was marketing linear-tracking turntables based on a Rabco (Jacob Rabinow) design.
