Sub question/problem

Hey guys, if this is the second post forgive me I couldnt find my first. My buddy gave me a sub and I hooked it up and everything is good there. My problem/question is that the actual sub speaker has a lot of movement, like when it is playing or when I just push on it. I feel that there should not be that much movement and it is killing some of my sound. Suggestions are greatly appreciated.

Thanks

 

Ya I could try and get that going for you. What the problem is, is that there is a lot of rattling which I think is comming from there being too much movement from the actual speaker/cone. when I push on the cone it seems like there should be more resistance and less movement, by movement I mean normal forward and back movement that a speaker makes this one just seems like to much movement, when compared to other subs. When I do push on the cone there is no scratching noise or anything like that, so I dont think its blown but I could be wrong. I think a more direct question is if there is a way to in a way tighten up the cone if that makes sense.
