Sounds like the surrounds on the cones have probably started to get weak and loose and therefore, the tightness has been lost. Do they have foam or rubber surrounds, some used cheap vinyl, as well. If foam or vinyl it probably has lost some of its original rigidity. Rubber would last much longer. The other thing is tha the crossover's themselves may have deteriorated but this is less likely. |

Who can do it, I'm not acquainted with any companies? Is it resonable...I've heard it is. Where abouts are you located? I think some of the guys might be able to direct you to some possible companies. Alternatively, you could shop PartsSource.com for a total replacement set of woofers. |

This should give you somewhere to start. |
