How much does stuffing actually increase the box size the driver "sees"? can i have a percentage roughly for different materials? The materials i am MOST concerned with are Dacron Egg carton foam Acoustastuff Polyfill and synthetic wool Ive always heard people say " that box is a bit small, might wanna consider stuffing it" or something along those lines. Yet i never heard how much it increases the virtual volume. Anyone feel free to answer, i want as many opinions as possable so i can get an average number!
