SUPER RARE Vintage ACOUSTIC RESEARCH AR LST Speaker MATCHING SET Serial # 166/167. The woofers need re-foaming but they still sound awesome. Both tone controls are working perfect not even scratchy. You may want to refinish the cabinets to remove any scratches. There is a small hole in one of the center screens (very minor). I could not remove the control knobs to remove front screen but was able to shoot some pictures of the woofers. They are very heavy speakers. Create listings that get noticed!
