    Will this 4th order work?

    I've built a quite a few ported boxes and I want to give 4th order a try. The sub is a Kicker CVR 15. I tried a 4th order box calculator online and I got 2.4 cubes sealed playing into 1.9 cubes tuned to 47. Does this sound like a good design for my sub? Also, how much port area should I use?

    Seems like the ported section might be a little small, 80inches will probably chime in and he designed a box for me (for a RD alphamax 15). Came to 2 cubes sealed, 4.34 Ported at 45hz (2 6" aero's)
