which driver for this diaphragma?

[Hofmannhp]

Hi All,

who knows which driver is the one for this diaphragma.
I found it in my numerous boxes for spare parts, knowing that it's there since several years.
The box shows:
No. 20275 - 11
and 20018
Re = 8,6 Ohms (maybe a 16 Ohm dia)

It looks like a 2420 aluminium dia with 44,5mm, but doesn't fit in a 2420. The voice coil height is only 3mm and the bolt holes don't fit to the 2420 bolts. The mounting holes are the same like the 2420 and fit.

thanks for any idea

looks like an altec 802 - the exposed lead wires are a clue

That was my thought, too- either Altec 802 or 902, probably.

Subwoof and Gordon,

your thoughts to the Altec direction are correct!!

With the help of Todd W. White's website I found out, that this diaphragma is for:
Altec 604, 604B, 604C that means the high frequency unit of the phenomenal coax driver .

thanks for your thoughts
