It may be bottoming out, where the cone/voice coil reaches it's mechanical limit.

How much power are you giving it, and how much is the sub rated for?

If you notice in the video, it's really not moving much at all.

looks like the surround is possibly not attached properly //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

ive removed the ring on top the surround is properly glued on the basket

thanks guys for the replies

here are some others thought on my problem, attached is a picture of the sub and other conclusion were that the spider should not be in that place or shouldn`t have a gap up to the cone they sed that it should be close to the cone, but i really dont know, the spider moves with the pole and cone freely //content.invisioncic.com/y282845/emoticons/confused.gif.e820e0216602db4765798ac39d28caa9.gif

did you drop it? looks like the magnet has shifted a little. maybe it's rubbing the vc?

edit: nvm
