Is this polyfill??


On the package says Speaker dampening pads.....

Should I put this in my box?? And how much my box'll be bigger??

speaker dampening is the equivalent to dynamat, its sound dampening...i'm not 100% sure it'll do the same thing but i think it would, i beleve the rule of thumb is 1in on each side of the box makes the box seem .10cuft bigger...something like that

This is ain't smthing like dynamat and it's much cheaper, 0.5 lb. is around $5....

Can't upload the damn pic...
