You have to shim out the voice coil...
Also its wise to let the glue fully cure 24hours before even attempting to play the woofer, some glues will not fully dry right away. Even 5minute epoxy says allow to cure overnight or 24 hours..
yah i saw the 24hr thing on the directions so i just pushed down on it a little bit and immediatley noticed it. how do i shim the voice coil?
