Hi Drogolf,

That larger sized driver was made by TOA.
- Looks to be a HFD-353

Back in the day ( 1970's + 80's ) TOA drivers were very much inspired by Altec ( while other Japanese driver makers mostly copied JBL ).

I've read that TOA's diaphragms are interchangeable with Altec ( don't have a TOA driver here so I can't confirm that though ).

Interestingly ( at least to me ) is that TOA alnico drivers seem to have been made by the same company that made the Coral ( Pro ) range of drivers.



:)

Thanks Earl.

Now I can research what these are best applied to. Of course having just the one isn't very productive.
It actually looks more JBL than Altec.
