    whats a good amount of port area for an E15k. I guess my question is, how do you know the best amount of area needed. Im looking at between 3 and 5 cubic foot box with a pair of e15k's in an isobaric configuration tuned to 20 Hz. Actually I will have about 5.5 cubes to work with, and the actul volume I end up with depends on how much volume the port takes up.

    So yea, the question is, what would be a good amount of port area?

    Ok, all I really needed was area....... Im nearly sure of my isobaric setup which will yield the equivilant of 6-7 cubes(3-3.5 cubs in isobaric) tuned to 20 Hz

    A lot of factors here. Depends on how much power you have. Depends if it's in a hatch or trunk. Well sealed trunk or not. You get the idea. As a general rule of thumb, keep the vent mach under 130ft/s.
