Harmo/kardon go play 2 speaker surrounds

[JANNAS]

Evening all, does anybody perhaps know if one can get foam surround replacements for the woofers of Harmon/Kardon Go play 2 locally. I think some of the other models use the same size woofer. Think its a 3 inch woofer. Otherwise I will have to get some from Ebay.
