    I read that RE calc wasnt accurate so

    Can someone verify that this box is 4.6 cubes at 29 hz?
    Box width:36
    Box height:16.5
    box depth:21
    wood thickness:0.75
    port width:4.0
    port length1:16.25
    length2:12

    Says 60 in^2 port area tuned to 29 hz. Just wanna make sure this isnt off because it cant be off.

    Port area is correct.

    Port volume is 0.67 cubes, including wall.

    Box volume is 5.84 gross internal volume; 5.17 net.

    I put all of my box info into the RE calc and found out that I was "tuned" to 27 hz. I peaked at 27 hz I would say its pretty close.

    4.47ft^3 before sub displacement.

    Not sure what your sub displacement is, but assuming net volume comes to 4.3ft^3, then your tuning is 29Hz.

    36x16.5x21 = 7.21 cubes gross,
    34.5x15x19.5 = 5.84 internal volume.

    The port is 4.0 (+.75 for wall) x 15 x 16.25 = 0.67 cubes.

    5.84 - 0.67 = 5.17...

    Re: I read that RE calc wasnt accurate so

    i think the whole issue was that it doesnt do the math for displacement, even though it allows you to enter it in.
