READ Pair of #5 ??Brand?? Powered Bookshelf Speakers 15 1/2x5 1/2x8 - $175 (Moorhead)

I got a lot of electronics from an older man that was close to 90 years old at the time, and that kept them in a seperate room in his basement that he had gotten at auctions from auctions, but I dont think he had gotten ant recently since they was a lot of dust that had developed from being stored so long.
He said most of the stuff worked that he had in the room.
I am not sure what brand these are, since it is not marked on them.
They have a different shaped connection cord in back, and I had nothing to test them with.
If you know what type of connection it is, or the brand, and would like to tell me, I would try to update the listing then.
These are in nice looking condition to use still.
