As some of you are aware Westlake is not in the habit of releasing much technical info on their systems. I was under the impression that these monitors having been rebuilt 5 years ago had a 2445 2" driver. While refinishing them several months ago I discovered they had 2441's not 2445's. Upon discovering this I contacted Westlake and informed them of the error in there initial
respose to my inquirys. We subsequently discovered the initial person who looked up the serial numbers made a mistake.

I finally recieved from Westlake, a complete copy of all restoration work and was extatic to discover these 2441's and 2426's have Beryllium diaphragms that were custom made through JBL. I am somewhat tempted to open them up but would have to remove the whole front baffle to get at the driver. The bracing is in the way to remove them.

One happy fellow

Interesting. I like the 2441 better myself.

Isn't that interesting. I hadn't thought that possible . I guess Westlake has a lot of clout . :D

I always said I love the 2441 above all others! regardless of brand.

BUT, I never knew JBL had OEM,ed Be diaphragms for the 2441 for Westlake!

Learn something new each day, thanks Ken!

They must really sound great!

Now we need to contact JBL & convince them To make a run of a hundred 2441 Be & 2450 Be diaphrams for us. :applaud:

If it was THAT good, they could probably sell many more than just a hundred!

Probably not as silly as it sounds, even for the 2426.

It would not be cheal though.

Where's Giskard?

I know a guy who rolls his own. If there was interest I could find out what it would cost to have a run of these diaphragms made. He said he is also modifying the phase plug... I am not sure what he was doing there. I did hear his drivers and they were very smooth and detailed. He compared them to the TAD 4001 and he preferred his JBL 2440Be over the TADs.

Widget, I know a guy that rolls his own too, but not Be.:p . What a super idea and I agree that this combo would be to die for. Nice of you to offer this item.


BTW:Hey Scotty j, you would really have some output with those SIX 2395's huh?

Hey Steve,

The upgrade is a cool idea, but the problem is that so many folks complain about the standard AL diaphragm prices. Let's see how many are interested at realistic Be prices... think at least two to three times the AL prices.:(

WidgetI would like to hear a proper be phragm in my fav compression driver!

Im thinking the price would be 500 or better per diaphragm! Quite expensive, but I could try one and see what it does! Let me get open, and running first, though!

Apparently JBL out-sourced these diaphragms. However, they were clear in the fact that JBL supplied them.

Widget " I was not worried about damaging these until you planted the seed! "

How could you do that to someone who's mentally ill?:bouncy:

Have a good one.

I bump this 6 years old thread to ask if anyone now knows the origin of these Westlake/JBL 4" and 1.75" Be diaphragms? Some early incarnations of brush wellman truextent diaphragms?

My understanding is that Brush Wellman approached JBL with the idea of selling their Be diaphragms over the counter and JBL declined. So Brush Wellman came up with the slightly different truextents to make available as aftermarket. Whatever the actual events, in the end it worked out for the best, the truextents are actually affordable. :)

Now if we could find a company that could build the cone kits to spec we'd be all set. :rotfl:
