It might be cheaper to solder a new one. I would compare prices, and decide if the price is worth soldering. If you want experience in soldering, go the solder route. Refining this skill will help later if you need to solder anything else.

Unfortunately, through our research we did not find anywhere for replacement parts. I would suggest ebay or other sites for ones that maybe already damaged and the speakers are still in working order. Sorry we couldnt help.
