    WINISD ported box help

    I have a JL Audio 12w3v2 D4 and im trying to make a ported box in WinISD beta. I put in 2.7 cubs and 43Hz. It says that the port should only be 5.61 in. Is that right? Sounds a little too short to me. Thanks, Andrew

    Re: WINISD ported box help

    holy hell! 43hz?! I hope this is a competition box...otherwise tune lower bro. But I would wager a bet that you dont have enough port area, makin for some port noise.

    Re: WINISD ported box help

    The length should be right around 8 and 1/8 inches. I used the pen and paper method so I'm almost 95% sure this is correct. Someone please correct me if I'm wrong.

    Re: WINISD ported box help

    Yes. Just have a look at Moe's plans for a general idea of what it would look like.

    Re: WINISD ported box help

    I just realized that this is a slot ported box you want to build. I'll need to know how much port area you want before I can go any further.

    Sorry.

    Re: WINISD ported box help

    All I need to know now is how tall your box is.

    To tell you the truth, its not really easy for me to explain it. Just keep reading and gaining knowledge, but in the meantime, you'll just have to ask.

    Re: WINISD ported box help

    it does not matter so i guess we can go 18in tall x 28 wide and 11.5 deep like WINISD said would be best. but you know more than me so you can change the height etc. is there some place where you learned? thanks

    Re: WINISD ported box help

    In order for me to give you a vauge idea of what your box will look like, I'll need to know the following:

    -What JL recommends for port area on that particular sub: ?
    -Net volume: 2.5cuft
    -Max gross volume(the biggest volume you can work with, and please specify what dimensions are what): ?
    -Tuning freq.: 35hz

    I learned all this on the forums just by reading every bit of information I could on building boxes. Its hard to catch on a first, but hang in there.
