MW Audio MW-6503-8: 6.5 inch Polk Audio Copy Woofer
These are new current production stock. The MW6503 6.5″ Polk woofers have been discontinued, so we had these custom made for us designed from the Polk Audio woofers. The parameters were closely copied to ensure similar output level and sound. In comparison to the original, it is very close. Overall, it is a great reproduction for many of the Polk Audio 6.5″ woofers. It is a perfect drop in fit with no modification needed to the cabinet. The screw holes are a perfect match too.
Great replacement for the following Polk models:
– SDA SRS1.2TL, SDA SRS 1.2, SDA SRS, SDA SRS 3.1TL, SDA 2B, SDA CRS and more.
– RTA 15TL and more.
– Mon 12 series 2, Mon 10 series 2, Mon 10B and more.
This woofer is also the closest replacement to the Polk MW6500, MW6501, MW6509, MW6510, MW6516, MW6600 and more woofers.
