Grilles for RT12s

teekay0007

I've got a pair of RT12s without the grilles and I'm looking to replace them with a new pair, or a pair that are in very good shape. I already called Polk's Customer Service and they told me that they haven't carried these grilles for quite a while. Also, if you know of any other speaker model that the grilles are the same, and are available now, please let me know. I didn't ask Eric at Polk, but I'm assuming none of the current Polk speakers' line grilles would fit since he didn't bring it up.

Thanks for any help anyone can give.
