I have a Hafler MSE104 10" 4 ohm subwoofer from the early 90s. This has never been mounted or powered. The box is massively uglified, but the sub is pristine. From the white stamped basket to the "Division of Rockford Corporation USA" sticker, this is just a cool piece of old-school SQ equipment. $30 gets it shipped CONUS. PM if you're interested.
