Hi, these are a pair of vintage floor-standing speakers with nice real wood veneer cabinets. The details about them can be found online. I have too many speakers, and am selling these because I have never used them, never even tested them. They are a pair of Harman Kardon HK-40 speakers with adjustable frequency control on the back, and they use a RCA connector. Just $10, please message, call, or text 613-617-6456 to come get them, thanks.
