    Classic AR 28S Speakers owned by me from new. They produce a classic sound from the heyday of hi fi and received great reviews at the time. They are in excellent condition with no marks apart from a small ding in the top corner of one (shown in the photos), and one of the screw masks is missing but is purely cosmetic. The foam speaker surrounds have been replaced to bring the speakers up to perfect condition. Im listing these with a low reserve, as I need to make space for some new purchases. They will make a great addition to either vintage or modern systems. They are heavy and solid, so collection only is preferred, as I dont have the original packaging.
