[QUOTE="DonH, post: 5207131, member: 594322"] ok so im designing a box for my ranger and have completed the final design! i have a few questions since this will be my first box build! the box below has an internal volume of 3.8546 ft^3. Is that to large to be a sealed enclosure? the subs i have are cerwin-vega HED's. sealed they call for .9 cubic feet each !! they call for 1.1 cubic feet each ported to 33 hz. I want to go for ported due to an eventual upgrade. If i wanted to port the enclosure to 33 hz how long of a port would i need? i know theres many sites out there that have calculators but dont trust em. N e ways i want the port to be 2.5 inches tall and 6 inches wide. any input will be greatly appreciated! thx guys!
