This is a single Polk Audio Original 6.5" Woofer Speaker MW6500 For RTA12 + Others. It measures 6.7 ohms on my meter.  It is in good condition and works perfectly.  It does have a scratch on the cone and the center cap is dented.  This does not affect the function ability at all, purely cosmetic.  It was removed from a working speaker. No magnet shift, no voice coil rub.  It measures 2-7/8" deep x 6-5/8" wide.   See all pictures for condition. This may work for other Polk models as well.  Please do your research before purchase.  Feel free to message any questions.   Combine auctions to save on shipping.  Please use the shipping calculator for rates via USPS mail.   Delivery confirmation is included.  Please Email any questions.
