Classic Realistic woofer, pretty good quality. The foam surround has deteriorated and needs to be replaced. Speaker sounded pretty good at medium volume levels when pointed upward. Rated 8 ohm impdedance, I got about 6 ohms on my meter. About 6" deep. Not sure how many watts it can handle but my guess would be between 50 and 100 watts.
Worth fixing.
