    retarded math question.

    how do you figure out square inches of port area?

    i thought area was ^3 not ^2

    specifically what is the port area of 14.5 x 1.5 x 27

    thanks.

    Re: retarded math question.

    Volume is cubic, area is squared. Take H x W for area, H x W x L for volume.

    Re: retarded math question.

    area= ???^2
    multiplying 2 numbers (w x h)= area

    volume=???^3

    multiplying 3 numbers (l x w x h)= volume

    your port case would be volume.



    aww man u guys beat me to it...



    A couple of hunters are out in the woods when one of them falls to the ground. He doesn't seem to be breathing, his eyes are rolled back in his head. The other guy whips out his cell phone and calls the emergency services. He gasps to the operator: "My friend is dead! What can I do?" The operator, in a calm soothing voice says: Just take it easy. I can help. First, let's make sure he's dead? There is a silence, then a shot is heard. The guy's voice comes back on the line. He says: "OK, now what?"

    Re: retarded math question.

    so why do they always say square inches of port?

    if i need port volume?



    well whatever it is... how much port area do i have? someone said
    it wasnt enough in my box building thread...

    __________________________________________________ ____________

    hold the flames... i see that ive got 21.75^2 of port... i guess thats a little small?

    Re: retarded math question.

    Two different things. You need to know port volume simply to know how much airspace the port is displacing within the box. The port area can have a direct effect on performance....too little or too much can be a bad thing.

    but youre running 2 15"s with 2600 watts... that i can understand a lot
    of port area for...

    im going to be running a 15A with maybe 800-961 watts... ive never had
    port noise even with a small round port with any of my setups...


    so lets hope...

    I am running a total of 6000 watts. 3000 per sub.

    But i would say that the are you have is fine. What is you r box volume.

    You have an electrical system capable of handling a current draw of (at best) 520A?? That's assuming amplifier efficiency of 75% and a constant 14.4V on the electrical system.

    squeak, that assumes that he is running 0dB tones at full tilt constantly.

    Sheesh... when did you become an alt salesman?

    Sorry, it's just one of those things, a pet peeve I guess; Nobody that I know of has the electrical system to run a true 6000w in a DD.....typically that's just what their amps are rated but they aren't actually pushing anywhere near that amount (yet they don't mention that part)


    I could run a 10kw amp in my car. But if I have it setup to put out no more than 2kw, or an electrical system that can't support 10kw worth of output, I shouldn't go around claiming to run 10kw.....just doesn't make sense.

    Re: retarded math question.

    the box dimensions are

    16 x 25.5 x 17

    with the port in question taking up some
    space and the driver once its in...

    bbp6 says i get about 2.2^3 net...


    holy crap monte... thats a sh1tload of power... are you deaf?


    assuming bbp6 and my building skills are at least close...

    what do you set a SSF for for a 31hz tuning???

    No, I do understand. I'd agree.

    It's just one of those things.
