Tweeter Identification

[Redox]

Hi, I have removed these tweeters from a pair of Mordaunt-Short MS 300 Gold loudspeakers from around 1988.
The markings do not give much away, but I believe that MS did not make their own drive units so these must be OEM supply.

I know they look like they came out of a Christmas cracker but does anybody recognize them?

Chinese made Audax probably. There are a few tweeters about of that type of design.

Yes, I think you are correct:

Audax TW6X9A

Thanks a lot....

It'll probably have a half inch voice coil, ferrofluid in the gap and a tiny neo magnet. :)

Can you identify the bass driver as well?

Hmm. I've seen Heybrook and KEF badged drivers with similar steel frames.

I don't think they are Kef, the frames look pressed!

They are pressed. Some of the KEF's were.

They look a bit like these:

I see you posted at the same time as me.

I actually have a pair of brand new (old stock) Heybrook drivers of this type. Mine are 8", those in the picture are 6.5" I believe.

Those are very close to the ones from these Mordaunt-Short's.
Thanks again for your help...

If you need some of those tweeters, I think I've probably got a few in the garage.

The bass drivers were Mordaunt Short’s own design and build. They were designed to be run full range without a crossover.

As mentioned previously, the tweeters are generic Audax types, found in many entry level speakers. This always puzzled me as the MS100 and MS300 were higher spec models with bigger price tags and the specially designed bass drivers were the main selling point. Why, then, would you mate them with some cheap generic tweeters when the tweeters in your cheaper models were made in-house and were better?!

Thanks for the reply.
