I recently received a broken 2240 on a 2245 frame. It looks perfect but the voice coil is stuck all the way in. Is there any way to know if it's a shifted magnet before taking it apart? In fact how do you determine whether the VC is jammed because it's destroyed or because the magnet has shifted (yes I know, and destroyed the VC.) my reason for asking is that I believe it makes quite a difference in the value of the frame. It's probably not worth very much if the VC is what is bad and nothing if the magnet has shifted. Thanks for the help. Pay pal got me back $200.00 of my $257 and if the frame is good I think I'm OK.. If the magnet is shifted I think I still got shafted.
