is it possible to turn a 1.5 cf ported box into a "2 cf" box only by using polyfill. theirs a website that goes into poly fill in depth alot and i forgot it, does anyone know what it was?
polyfill goes 1 pound per cubic foot of enclosure volume. that adds the equivelant of 10% volume. no way to add more than that with polyfill. just need a bigger box.
