Help with building custom box
I am building a few custom sub boxes for myself and some friends. I am using mdf board and plan on making a few different sizes. My question is, what is polyfill? i have heard some people talk about having the inside lined with polyfill but i have no idea what it is. is it a spray on insulation of some type. Can somebody please tell me what it is, if it helps and where i could get it in canada.

it changes the acoustics of the box to make the box "seem" bigger, you can play around with it to see how much you want for your sound.
