Classic P21WO20-08 8" Poly cone woofer
Originally a Vifa of Denmark product, this batch was made by their sister company at the time, Peerless of Tymphany in China. In prior years, we had Scan-Speak make these for us. Those have sold out and will not be available again. There are no longer parts for them to build more. This is also the last of the Chinese version too.
