Quadral 26" tieftoner suche.

Hi to all you Quadral fans.I am looking for a pair of woofers
by Quadral for their Vulkan MKIV-V and the Montan MKIII-IV.
These are marked on the magnet :W250/50/9/PF/AA and i think
are 8 Ohms...I want two of these in working or not condition
(but repearable!).I will prefer the ones with their decorative
aluminum rings with the four "ears" if someone has them.
Feel free to email me at [email] konjohn@hotmail.com...Thanks!
P.S.Also if anyone has it, a (one)Titan MKIII-V woofer.
This is marked as W320/64/8/PF/AA again with the aluminum ring
if anyone has it!
