After you brush the dust out of the speaker, front and back, try this: remove the "padding" somebody put in there. Dip your finger in water and thoroughly dampen the front of the cone, all over, stay a half inch away from the center felt, and wet the outer corrugations also. Leave the speaker sitting face upwards overnight to dry. Many many times this will correct the problem. The cone absorbs moisture from the air and warps, making the voice coil drag, and the cone dries out in that position. When you dampen it, it relaxes and the spider, which positions the voice coil in the gap, is able to pull the cone back into alignment.

If that doesn't work, it can be aligned another way with shims.
