O.K. Thanks for your input. Bear with me because I'm not 100% sure on the vocab everyone is using.
I took the woofers out and when I shake them one has some stuff loose inside the black center cone. Is that the dust cap or dust cone? Anyway that must be where the noise is coming from. Does that mean the woofer is broken? It moves in and out evenly and makes no noise.
Thanks angain for any help.
