Does anyone use poly in their enclosures? Anyone have experience with how it effects volume/ tuning/ efficiency? If you use fill instead of batting what methods do you use to keep it inside?
I'd like to use it in a temporary prefab thats 3.3 ft^3 (b4 port/sub displacment) w/ a 41hz tune. I'd like to shoot for 4-4.5 ft^3, how much fill will achieve this? I was told 1lb = .5 ft^3... In that case 2lbs should net 4.3. How will this effect tuning? My vent measures 3w X 11.5t x 12.25d (straight center slot)... In theory the same size port @ 4.3 equals 35hz... Would this hold true in the real world?
