    box for xxx 15

    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.

    *Vb = vol. in cu"
    **R = sq.rt. A / Pi (for square/slot port)
