Pull the woofer out and see. Is the magnet still firmly attached to the rear?
Does the cone move in and out evenly with pressure straight down from your
fingers or does it scrape? If you carefully cut open the dust cap (cut
around the outer edge so it can be reglued) you can see if there is damage
to the voice coil or if the voice coil has come off.
If the driver is damaged, send it to a speaker reconing place and have
them fix it. Speaker Factory in Gaithersburg, MD or the Circuit Shop in
Kentwood, MI both do good work on consumer drivers.
