I am looking for a pair of the old ESS AMT, 10" woofers, bad foam is fine. I know every one who ever owned ESS AMT's HATED those woofers, but I have a use for them. So if you have a set hanging around you have no need of, let me know. Should have numbers such as 680-0004 or 680-0010, and others on the back. DC resistance will measure around 5.3 ohms.
