Altec Diaphragm on Ebay

Indeed he do! Speaking of which, you done any more on those or spent all your time digging out of the snow?

GM

12"+ here so was doing plenty of digging.But also waiting to get my woofers back from GPA, should be soon.One other thing GM I asked Bill about doing a full diagnostics on them before sending them back a long with the T/S parameters told him not to send back until they are near factory spec.I told Bill that I will test and measure them when I get them back it will help me determine if I'm doing accurate measurements with my gear.

I just wanted to make sure! With the shipping charges being twice as much as the re-mag costs can't afford to make mistakes. :2thumbsup:

Understood.

I forget, how do you measure T/S? Vas in particular can be tough to get right consistently.

The woofer tester WT3, and I did the added mass method for VAS.

Well, the 23744 ended up selling to the highest bidder at $103.52. BTW, did anyone read my post #10 in this thread or did it get buried in this obscure thread? Wondering if anyone has any theories as to why GPA doesn't offer the 23744 when they offer so many other (less well known/less sought after?) diaphragms. I offered up a few theories--wondering if any of them are on the money?

I copied and pasted this into "google translate" to see if it was spam and this is the translation:

"hello everyone!
I am the purchaser of the membranes altec 23744,
proud owner of a pair of model 19, I noticed a difference between two
802 8g. one is mounted with the standard capsule 26___ and the other with the model 23744.
Comparative listening on different type of signal shows a sharp rise, a "transparency" with 23,744 ...
I have a spectrum analyzer, but not the possibility of publishing. I will wait to receive the package and will certainly keep you informed!

ps: apologies for not being able to answer correctly in American ... sorry"

Anymore on this topic? I'd love to see some new and accurate graphed comparisons. I have model 19s and this has been bothering me as I have the new diaphragms in them and wonder what (if anything) I am missing. I do feel that they are rolled off a bit tho....Maybe just the character of the speaker? Or maybe the newer, thicker diaphragms? I do know that the review of Model 19s from the 70s in one of the audio magazines mentioned that they had a mellow top end with a roll off from 12k on up. So maybe that's what I'm hearing. Any help is greatly appreciated! Thanks
