    Re: Subwoofer Box help!!!!

    look in the book that came with your speakers if you have it it will tell you the recomended air space go with that is always a good rule of thumb or learn how changes in the box will change the sound. There is also software available that will guide you in the right direction if you know what your looking for. If you don't have the books check the manufacture website. Don't waste your time on Rockfords site though. They just put all their new product line that is hitting stores at the end of next month on there and you can't find any of the old specs. However if you need them let me know I have Specs on all Rockford product at work in my notebook.

    well what i was looking for was the deminstions that would make the speakers sound the best. How would i figure up 1 cubic ft. Pretty much you could say that i am needing a subwoofer bow building book for dummies.

    Re: Subwoofer Box help!!!!

    if it's a square box.....Length X Width X Height will give u the volume, then u divide that by 1728 and you get the cubic volume.

    for example a 12" square box would be
    12 x 12 x 12 = 1728
    Divide that with 1728 and u get 1 cubic ft of volume

    So that is one possible dimension for ur box

    The same. if the internal volume is the same as a wooden box and you build it 1/4" thick it would be the same as a 3/4" mdf box. 1/4" is packed glass meaning no air or anything between layers but a good stacked thick layer.
