Hello,

I'm hoping someone or some people with a greater knowledge of speakers can clue me in as to what may be bothering one of my Bose 501 speakers.

They seem to handle quite well. I like the bass(not suggesting by any means it's the greatest). I enjoy the stereo field but then I hear this fatigued almost distressed sound on the one speaker. I describe it as something is dying. A muffling sort of sound on the woofer and low volume on the tweeter.

This sound has been with the speakers since I picked them up. I don't have any 4 ohm receivers around so I had to try it out on a Sony STR 6065(which I believe is 8 ohms) and a Kenwood (90's era) which I think is 16 ohms.

Could they be causing a speaker to crackle?

I've tried switching wires around but nothing. Voice coil? It seemed to clean up a bit with more volume but now it's getting worse? Any ideas?
