Polk MW 6500s early for monior and RTA 12

Nice pair of early Polk MW6500s. I have one or two spares so these need to go to someone else. These are the early ones with the grey fiber surround cover. Used 1977 to around mid 80 in Monior 10s, 7s and 5s. and early RTA 12s In nice shape asking $25 each thanks,keith
