Replacement woofer for S15 bookshelf speakers

bryanj25

Hello! I have a pair of Polk Signature Elite S15 speakers, and the woofer on one of them is blown. I've removed the woofer from the cabinet to get the part number (which is RD9534-1), but I can't seem to find the part anywhere online, and Polk phone support wasn't much help. Would the woofer from the newer version of these speakers (ES15) work as a replacement? It doesn't have to be a perfect match acoustically. Thank you!
