    This question is directed mainly toward greg but anyone feel free to answer. I'm working on a box design for a friend's sister's s series blazer. Going to use a JL 10 W0, when calculating box volume do I subtract the volume the sub itself takes up? If I remember right I subtract the volume the port takes as well correct? Since my port will be inside the box.

    You could just check some boxes online for measurements and volume. See how they calculated it? Wish I knew more..

    I believe you have to subtract the subs volume

    LKJR,

    You are right....subtract the speaker volume AND the port volume from the "net" box calculation. The JLAudio website has published the speaker displacement specs for you already....so just look up the specific speaker you're interested in. Just look up the "Data Sheet" for the 10W0 and you will see it there.

    Don't forget....."net" box volume means you also have to subtract the "thickness" of the box materials you're using too. That's actually the biggest "loss" you'll see of all the things you need to subract-out!

    If you want, publish the box dimensions, material thickness, and port diameter and length, and I can double-check all the calcs for you! It's sometimes nice to make sure someone else gets the same answer you did....[​IMG]

    thanks bud,
    I'll try to do that when I get it designed, would be nice if it was a simple design but i'm making it similar to yours just opposite, It's going on the pass side rear, of the wheel well, my design has the port facing the front and the sub firing toward the drivers side. What do you think on that, I think it should probably be fine and give enough bass to hear well

    That design will work as well as any other....as long as the box is FIRMLY connected to the truck the bass will "couple" into the chassis and give you good "vibes" everywhere....

    Post some pics as you go..... [​IMG]
