    question about port sizing

    i am about to build an enclosure and i noticed when going through the calculators on 12volt.com that the wider i make the port the longer it has to be to achieve the desired frequency.

    what are the pros and or cons to making the port bigger or smaller

    Re: question about port sizing

    The larger the port opening the more air flow you'll have, which will reduce port noise and yield smoother air flow. Too big is a problem, as is too small. As a rule of them the port opening surface area should be at least 12 * the square footage of the box.

    So for a 2 cubic foot box the minimum port area should be 24 inches.

    To calculate port area, multiply port width time port height.
