    Icon31 Can someone check these numbers please?

    These are straight from the RE Enclosure Calculator, I just need confirmation they are not completely ducked up.



    Box Width: 35
    Box Height: 17
    Box Top Depth: 20
    Box Bottom Depth: 20
    Wood Thickness: 0.75
    Square port height: 15.5
    Square Port Width: 3.5
    Square Port Length 1: 15.75
    Square Port Length 2: 0
    Total Port Length: 21.75
    Square Port Diam.: 8.311031542
    Square Port Area: 52.25
    Square Port Volume Internal: 1179.9375
    Square Port Volume Displaced: 1191.1875
    Box Volume(Ft3): 4.87
    Box Volume(In3): 8414.9375
    Tuned Frequency(Fb): 32.8371999648271


    Im going for a box around 4.5 Ft3 with a tuned freq. around 32-33.
    These numbers are before subwoofer and internal bracing displacement.

    I just wanted to know what you guys think? Does anyone see any glaring flaws that I may have missed?

    Re: Need help understanding tuning hz.

    It is for a 15" CVX

    Kicker recomends 50 sq. in of port for a 5 cubed box, however I can't fit a full 5 cubes lol. I can definitely live with a little less tho.

    As long as I'm between 3-5 cubes I should be alright they say(kicker).

    Should I go ahead with the build?

    Or do you think the port is too small?
