Materials to reduce sidewall flex & vibration ?


I am wishing to reduce sidewall vibration without adding reinforcement 
within the cabinet. I'm curious about fiberglass and other products that can attach/bond 
permanently to the sides yielding the highest stiffness to weight ratio.

Please help me understand this. Is this a work around for a poor cabinet design-build? I can't imagine having to do something like this to my speakers.
