Picked up an old set of Polk R8 mini towers for the price of a few Big Macs, with one being described as sounding "thin".
Got 'em home and found the surround of one woofer was about 30% detached from the frame. Fixed it up and they sounded quite good.
Decided to test with REW just to see if they match up in response and output, and noticed a "rattle" from the cabinet I did the repair on.
Ran a 25-200 test tone and poked and prodded. 'Turned out the lip of the surround was also detached from the cone for about 2" of the circumference, but this damage was not visible because it lays so perfectly flush on the cone.
Glued it up and no more odd noises. Win!
Borrowed pic. Because speaker posts without pics are boring. Graph pic for same reason.
