I'm trying to locate the Vifa datasheet for the M22WR-09-08. I've found one from MASS and the M22WR-09-06 but no luck with the 8 ohm version.
Oh, and test the Fs on it. The specs sometimes say 26hz--which is true for the 10"--and sometimes 30hz. I tested mine and it measured at just over 30hz.

Thanks... the one from Poland is the one I'm after as it has the original DST FR and impedance plot.
Hi Mos
Long time no see... where ya been? I've already used it in a few speakers and the latest is this one.

I didn't measure it but have some MASS data which did show an Fs=30.21Hz and other variations in T/S parameters. However, when they were modelled using the Vifa and MASS data, they came out about the same.... cool.
It is a great driver and one of the best 8" out there. I've just been playing my silly games and checking out the current crop of 8" drivers (not too many these days) and the only ones that come close for my purpose are the Scan Speak 22W8851T00 and 22W8857T00.... plenty $$$$$$. That's why I needed the original Vifa FR and impedance from DST so I can compare apples with apples.
Cheers

I am also looking for the data sheet.
Unfortunately "Tymphany.com" has delete all pdf files from legacy Vifa/Peerless products
(after close the weblink "www-d-s-t-com")
also about Internet Archive: Wayback Machine
I don't find any information.
Whocan post a data sheet ?
