Hey guys, I just acquired some vintage Pioneer HPM-60 speakers from Goodwill. One of the speakers works perfectly, while the other one has a blown midrange and cone tweeter. I am having some issues acquiring parts. I have been looking closely on eBay for some of the parts, but I really don't want to pay more than what I paid for the set of speakers. Does anyone have any recommendations on how to acquire OEM parts or at least parts that are similarly spec'd to the OEM drivers? Also, from what I can tell the HPM-40 - HPM-100 use the same tweeters. Same thing applies to the mid-ranges.
