Since a number of folks here have either the Carver Original Amazings or the Carver Platinum Amazings I thought I'd post this very helpful info on woofer refoam and OEM replacements.
If you want/need to have your woofers refoamed, contact Roland at:
2125 SW 19th St.
Gresham, OR 97080
He also repairs all Carver amps, etc. with OEM parts. Very nice and helpful gentleman.
If you want to buy brand new OEM drop in replacement woofers, contact http://www.dynavox.com/
Click on products, then 12" woofer. The replacement for the Original woofer is Part # SW-1220FL and the replacement for the Platinum woofer is Part # WP-1220. These are the exact same as the ones that came with your Amazings and they only cost $25.00 each.
