Default Classic Audax Bextrene Units from 80s

My friend has some Audax 8" Bextrene woofers from the late 80's - 8 of them. They have arubber surround that is inverted. They appear to have the smaller magnet and not the huge magnet that I some audax mid-woofers have.
Also some 1" soft dome units with ferrofluid from the same era.

I was thinking of using them in a MTM in a transmission line. Are these drivers even worth re-using?

For sure they are. The baskets need damping (but that is the case with most drivers anyway). Got any numbers, i might be able to dig out factory specs.

Default Looking for Audax bextrene driver for Tangent RS6

Hi,

I wonder if your friend still has the Audax bextrene drivers? I am looking for a replacement driver for my Tangent RS6 speakers.

Default audax bextrene

There are many different opinions on which bextrene were the best . One thing I know from using so many is that the Dalesford could play cleaner and louder then the kef and audax, especially the oem fried dalesford versions. The audax HD17B37R4C12 were the first raw drivers i ever purchased that were not part of a kit. I still use them as t-line subwoofers with bose cube drivers in micro t-line.

What are you looking for? I have a pair of Audax HD 20 B 25 J drivers that are pretty much as close to NOS as you can get. In original boxes.

I'm just doing a hardcore DIY project with NOS Audax bextrene cones and am puzzled how poorly these classic units seem to harmonize with the original paper voice coil formers compared to modern Kapton formers (just from knocking on the formers from the rear). I'm looking forward to see the plus in resolution compared to the Spendor speakers I had owned for ten years.

I used them in the late 70s. I used four on each side in a stereo transmission line the size of a coffin and they did great. I also used them in a two way with the Audax 25mm soft dome, which sounded good, but not great.
