I picked up a pair of RT8's for $65 but the woofers are scratching at low volumes. I'm afraid they're blown. I would like to replace them. The replacement stock at Polk is depleted and I was advised to replace the speakers as a whole. I would like to refurb these as they're great speakers, and they match my other same-age setup. Do you have any suggestions for replacement drivers? I could not find suitable ones (at least I think) on partsexpress.

Thanks
