I have bought a pair of pioneer HPM-500s at a thrift shop. they were in great shape except the surrounds needed replacing. i replaced both of them and in one of them the voice coil is fluttering at a low vol. they were doing it worse but i took the dust cone off and bent the coil a little and it fixed it pretty good but not all the way. they are a very nice sounding set of speakers and i need some info that can maybe fix the fluttering or help finding a new woofer. so if you can help let me know.
