I'm curious about using the spray-on material used in truck beds sprayed on the internal surfaces of speaker cabinets to reduce resonances. Does anyone have expeience with this or a similar technique?

That material does almost nothing for resonance control.

If you're set on a diy method, this does work well when properly applied.

We stock and sell that product. It is a nice durable and easy to apply coating for the outside of a speaker. However, it does little to nothing for resonance control.
