I have owned these for a few years and have thoroughly enjoyed them. These are supposed to be mirror imaged speakers, however, these are two right sides. I have enjoyed them with no complaints. There are no decals on them to show serial numbers or model number but from the bi amp speaker terminals I know they are the more rare and newer 303A’s. I took a lot of photos to show the cosmetic condition. There is a little bit of waviness on the bottom and right rear bottom of one of the speakers. There is also a little bit of separation on the bottom corner. I have never owned a pair of speakers that puts out a low end like these guys. That being said, they need at least 200 watts and a 4 ohm stable amp. All drivers performs very well and they sound phenomenal. They are pretty heavy at 54 pounds a piece. They do not come with the stands shown in the photos.
