For sale: (4x) Vifa M18WO-09 8-ohm woofers

For sale: Four (4) clean, lightly used Vifa M18WO-09-08, 8-Ohm, 6-1/2 inch woofers.
The bad news: Two of them have a small section of the outer magnesium basket neatly removed from one edge (see pic), while the other two are unaltered.
Otherwise, it's all good news. These look great: cones, spiders, rubber surrounds, terminals, all very presentable, and measure the same 5.9-6.0 DC Ohms.

U.S.A. shipping only. Asking $90 plus actual USPS ground shipping cost for the set of four woofers as seen.

I would also sell these as pairs. Asking $40 for the truncated-edge pair and $75 for the unaltered pair. Plus actual USA shipping.

These (with a truncated basket) were used in the Sonus Faber Concerto, and I've attached the 1998 Stereophile review for the measurements of the speaker and crossover.
