Blown polk woofer

scionide

So it seems my left woofer went out..in the last week it cut out and came back, but now it just does it all the time and it makes a noticeable rattling noise when it does work. About a year ago it cut out randomly for a few minutes and came back, perhaps it was always defective. I think the voice coil is damaged as it makes a "tinny?" noise when I tap on the cone now.

Anyways they're Polk DB6501s, does anyone know where I can buy just a pair of woofers themselves, I haven't found anything.

If I have to replace my entire component set, any recommendations within a similar price range? I'm running them off of my headunit *Kenwood DNX6980* and have a pioneer 10" sub as well.
