Genuine pair of grilles (frames and cloth, no badges) removed from a pair of Acoustic Research AR4xa vintage stereo speakers. Overall good condition with intact frames, but one of the grilles has a tear and there is some minor staining. Please refer to the pictures as they are part of the description. Dimensions are 8 3/4″ by 17 3/4″ approximately. I took a couple pictures of the grilles next to one of my AR4x to show that they are seemingly identical in appearance, width and height.
