ok can sombody give me a link the gives me general description of Cuft and box building.... ive built a box for a 15" but i had no idea that i had to take cuft into consideration.... if theres no link and u feel like explaining what i want to know is higher the cuft better? or the lower? mostly for spl, but if you could explain all aspects that would be great, and also for sp i would want a vented box not sealed?
ur 15 should have at least 3 cubic feet, depending on the sub. that would be 3 cu feet plus the port, if it is ported. if it is sealed it could go down to aroun 2 cubic feet.
