    Tell me what you think

    I'm working on a design for a guy on another forum for a single sdc2.5 12 off 500rms. Its for a single cab f150. I'm going to have the sub firing forward with the port firing towards the passenger wall. I want to use an aeroport but have never designed a box with one before. I understand that you can get away with less port area when using aero ports, am I correct?

    Anyway here is the design so far. Tell me what you think and what I should change.
    Box:
    13.5 (H) x 42 (W) x 9 (TD) x 10 (BD)
    Port:
    3" x 5.5" long (used precision sounds calculator)

    That should give me roughly 2 cubes after sub and port displacement tuned to 38hz

    Comp amp: Crescendo 1000c4
    Sub stage: (2) AQ HDC3 10s in 2.3 cuft @ 38hz
    sub amp: Crescendo 3kw
    Electrical: Mike Singer 250a alt w/ext regulator, D3100, NSB100, D680, 50ft of shok cca
    149.5 @ 39hz and climbing...


    Plenty of refs between here and caco....

    3" 5.5" long? doesn't seem right.

    more like 4" 22" long.

    well according to precision sound's calculator for 2 cubes @ 38hz with a 3" port it should be 5.4" long with flared ends and 4.4" long w/o flared ends. Unless Im missing something.

    I've never used aero ports but I feel like Im over analyzing something

    Re: Tell me what you think

    I revised the box design to be
    42" (W) x 14 (H) X 8 (TD) X 10 (BD)
    aero port
    4" x 9.75" long
    giving me 2.02 cuft at 37.8-9hz after port and sub displacement.
