These speakers sell for over $200,000 grand new, I find it pretty amazing they use a JBL component. Rock on JBL!

Have you contacted them to ask why? I bet they'd be able to give the best answer.

I got on the phone with some people over at Westlake and they told me that they use the 076 simply because its excellent. Furthermore they informed me that they are currently in negotiations with JBL because JBl has stopped making making the tweeter and they're trying to get them to continue to make it for them. Unfortunately from they're perspective they told that JBL has no interest continuing to produce the tweeter. (We all know JBL maybe 25 years or so ago moved away from building quality speakers and components) Pretty sad, Westlake said they will have to completely rebuild their SM-1 speakers or simply make a new one if they can't get a hold of some 076's.

Well since JBL have sanctioned Eminence to make D130 clones for Fender I would guess that they would not give a hoot if Westlake got 076 clones made by Song Yo or Wung Soo as long as there was a few $$ heading to the Cayman Islands. :crying:

It just registered with me that these go for $200k. At that dosh they could easily have the lens / horn cast for them and cull sufficient motors and dias. Where there is a will there is a way.

I would think 2405 slots with the right diaphragm in them would be comparable. There are lots of those out there.

076's are an interesting combination of parts. A standard AlNiCo 240X / 07X motor assembly with a diaphragm that is a 075/2405 mashup. The inner horn is the same as used in the 2404 as is the 1.720" base diameter phase plug used in the "hi-fi" model 2404 with a D16R2405 diaphragm. So the only two uncommon pieces that make an 076 are the diaphragm and the outer horn.

I wonder if the 076's supplied to Westlake had the 2405 or 076 diaphragms?

Then there is always the TAD ET-703... it is in production and is superior in many ways, but because it is available, I suppose it loses a bit of that unobtainium quality required for a $200K loudspeaker.

Widget you are in plastics molding , as I recall , may be wrong, but if you are perhaps you should give them a call.
It does not seem an impossible obstacle to get around and I have no doubt that JBL Pro would furnish whoever with the relevant drawings etc , that is if they havn't lost them in a flood / fire / removal
Come to think of it there is a lovely wee niche market out there for a quality cloner. ;)
Does the 076 exist as a ferrite ?

I think you can request Westlake to build SM-1's with TAD ET-703's, I remember seeing Ken Pachkowsky post a photo of SM-1 Towers with 703's... can't find the thread though... :dont-know:

There is a ferrite version of the 2403 pro counterpart, the 2403H.
