Default Repairing an Infinity SM225 Woofer?

I've got a pair of Infinity SM225 towers in my basement (hooked up to my NAD amp, which are both used primarily for records). Anyway, I noticed that the 12" woofer on one of them is blown out (that or it rotted). I've been trying to find a replacement online, but haven't had much luck. I noticed that Infinity used to sell a replacement for $200, however, if this were still available and not discontinued, I paid $100 for the pair so I can't really justify spending $200 to fix one of them (I bought them from a friend during college about five years ago).

My question is, it seems like the only option (if I choose to keep these) is to find a different 12" woofer to replace it with, and then replace it on both of them so they're matched. Any suggestions?

This site has the original specs: http://www.infinitysystems.com/home/...=US&Region=USA

Thanks!

Put in one of these. It is listed as approximately the same volume in a ported enclosure. Are the ports what is needed? Probably not. But I read a bunch of user reviews, and it sounds like it won't matter anyways

Or, If you have a little mechanical skill and want to save some money get a surround Kit:

Good luck

You will not find many woofers that are as efficient as those, I wouldn't try replacing them unless you carefully measure the good one and find a good match.

Refoam them. When my speakers' surrounds rotted, only one looked bad at first.

Refoaming is not hard, just fiddly and a bit time consuming.

Hi,

If the bass driver is not blown, refoam both of them.

Thanks for the responses. Yeah, I started inspecting it a lot closer, and I think the driver is intact. I ordered a refoaming kit, I'm curious how well it works.
