[QUOTE="Ivan Beaver, post: 81762, member: 30"] Re: strange subwoofer thingie A cracked magnet and a shifted pole piece (often called a shifted magnet-even by me :( -which it could be) are different things. The shifted pole piece means the center pole (back plate shifts-either from the magnet becoming lose or the back plate becoming lose) is pinned up against the top plate-trapping the voice coil (and cone) from moving. A cracked magnet will no longer have the strength it used to have-therefore reducing the output level (less magnetic force to interact with the electromagnet of the voice coil. [/QUOTE]
