box for xxx 15

[phrozen_lad]

Hi guys i have an 05 xxx and after a few word with a few people have come up with the following box spec - 4cubes @35hz. Can someone have a quick look over to see if the box looks ok please? ie. the port area, whether the RE designer has calc'd the port tuning/length correctly?

thanks guys

using the formula in my sig, i get 21.42" should be the port length for 4cu' @ 35hz w/ 49.5sq" of port.
