One of my local buddies had these in some KEF or other (non Polk) speakers that someone replaced the originals with before he got them.
He now has acquired correct woofers so I bought it from him.
Woofer surrounds have engraved Polk audio on them and some numbers.
It's the same number in both.
There is nothing else in the magnet or anywhere.
It appears that the sticker with model number fell off somewhere.
Any idea?
I'll take few snaps when I get home.

Sonus Faber Concerto Grand Piano, Klipsch, B&W DM602.5, Epicure 20+, T/E 280, 100V, Polk.
Subwoofers: Monitor Audio, B&W ASW300, Triad ProSub Bronze.
