This is about polyfill ?

Question

how much polyfill do i need for a bandbass enclosure? or do I even need it?? it holds 2 12in subs im not so sure of the dimensions but... u know!

Answer 1

you need to check the specs of your subs and if the box is too small then you would use 1 to 1-1/2 pounds of stuffing per cubic foot of box volume and its used to slow down sound waves inside the box, making the subwoofer perform as if the box were bigger

Answer 2

1/2 lb. per cubic foot.
