So, am I the oldest living JBL employee?
Wow, what a flood of great memories.
Thanks for that link.
Rudy,
Well, you could mount it in the wall and let the back end of the D123 exhaust into another room. That would be best for an infinite baffle. For an open back, or sealed box, the formula...
Looks like a home brew "C40 style" horn-loaded system in an "Olympus style" outer shell.
Actually, it was just one guy that convinced Bill Thomas to come out with an actual Musical Instrument speaker line instead of selling home hi-fi speakers. More info here:
...
I suspect they were D130F's, since it was well known by that time that the F series were a lot better at surviving outdoor events (compared to the normal D130's).
The original D140F should have a ribbed cone, a flat, edge-wound copper voice coil, and an aluminum dome.
The later C36/C38 cabinets had a removable grill cloth (like a screen door) that was held in at the bottom front of the cabinet. Lay the cabinet on its back and look for a long slot just behind the...
This is truly a sad day for me. I saw "Duck" at the Monterey Pop Festival when he played with Booker T (as part of the MG's), and again behind Otis Redding. He was one of the greats.
Lay the enclosure on its back and remove the two 1/4-20 bolts (located at the front of the bottom lip.)
And that's the main reason I went with the aluminum dome on the D140F: You could see they were JBL's from a mile away.
My memory is probably somewhat faded after all these years, but I seem to remember that the lightweight curvilinear cone had some breakup around that frequency. Try sprinkling some talcum powder on...
Simple answer:
Back then, we lied.
Even though they're marked as 16 Ohms, they were all really 8 Ohm speakers. The DC resistance should be around 70% of the nominal rated impedance, so an 8...
As I remember it, George Augspurger reworked the 4310 crossover for the L100. I don't know what he did to it, but George was responsible for the changes.
And that's exactly the way it was used on the cloth surround of the JBL D123, to simply seal the surround cloth. I decided to use the same stuff primarily to prevent surround disintegration (and to...
Looks like a C34 cabinet with a 001 system, except the owner started off with a D130 and added a 175DLH and the N1200 crossover later.
That could be Rudy Winegarten's old place; he was a big JBL dealer in the late 50s/early 60's. Heading west (towards Beverly Hills), it would be on the left (south) side of the street.

If they ever get around to paying me the royalties for the new Trident nearfield speakers I designed, I'll be traveling a lot more and I may take you up on that invitation.
Thank you. I still feel inside like I'm a little over 20 years old, but the outside sure ain't keeping up with the inside. :(
Today, I'm not gonna be sitting around feeling old; I'm off on a...
Steve,
By the time I stated at JBL (in the late 50's), they had it down to a science. One guy in the cabinet shop built the whole thing (Bill something?; I remember he lived in Sierra Madre). By...
If it is from 1954, that predates me. I started there a few years later. The board below the 375 looks hand cut, and I don't remember the crossover cutouts looking that uneven. Plus, the...
It's very nicely done, but it doesn't look like a factory Hartsfield; too many little things wrong, sloppy, or at least, not standard JBL practices.
Still, a great piece, nonetheless.
No JBL content, except for an ex-JBL employee playing Dobro.
But I put down the Dobro and grabbed my iPhone to record this informal jam session at banjo player Joe Hood's house:
Bluegrass Jam...
Sure, Sweden's no problem.
