It'll work for awhile but from the sounds of it you will need a recone eventually. I've done nasty things to subs with a rubbing coil and they still played strong although that rubbing noise gets on my nerves lol

So it was bought used? I guess this is the reason the guy was selling it.
But to answer why it sounds like its rubbing, my best guess would be that it has seen some heat. When the coil heats up gasses are released from the glue used to laminate the layers of the coil. Obviously the inner coils hold heat more so then the outter, or exposed part of the windings. The gasses create pressure. Pressure always has to go somewhere. What tends to happen is the built up pressure on the inside will create a bubble in the former. So now it rubs on the pole, the sub will work 100% fine still only issue is the annoying sound. Ask me how i know this? lol

#1 reason for coil rub on flat wound coils ^^

not the case at all. The other 7 are fine(all were used on 1 DAT 8K). Just got a email friday regarding this sub that I shipped in Feb.

Richard, we'll work out the details via email.
