Does anyone stuff their boxes with polyfill? If so, how much should I use in my .75 cu. ft. sealed enclsoure?
right on there.If .75 is the size the sub needs - none.All polyfill does is cause the box to function like it's bigger than it measures.
Depending on the amount of fill you use it can simulate an enclosure 10-30% larger.
