    Re: 4th Order Design

    its easy, do a 2:1 ratio which means for every 1 cubic foor sealed you would do 2 ported then tune the ported section to 40-50 hz

    for your sub i would do 1 cube sealed 2 cubes ported at 45 hz, use re box calculator to make the ported section or the12volt.com

    also bandpass designs have a pretty wide band width

    tune it to 42 for a lower response and more air movement

    Re: 4th Order Design

    Ummm... I would never use RE Calculator... and there is a lot more into designing a 4th than a 2 to 1 ratio...
    I know how to use Bass Box Pro and WinISD... just would like someone that does this all the time and can get more detailed in the design than I can with everything else

    Re: 4th Order Design

    Why not hit up one of the box designers on the forum. Not every sub will perform well in a 4th order. The Fs looks fine, but the qts is rather low for a 4th order. That sub will probably perform better in a ported or 6th order.

    Well Buck was designing the box for me till he got sick... and most everyone else usually takes a week or more to do a design

    Re: 4th Order Design

    From my understanding, drivers that work well in 4th orders have a lower Fs (which your sub has) as well as a qts of .5 or higher. I would maybe ask for a 6th order design, or just go with a regular ported.

    Re: 4th Order Design

    As stated above .50 or higher for qts. You can also use the drivers EBP, which is Fs/Qes. I believe if EBP is less than 70 go 4th order and greater than 70 go 6th order, but not positive on that.
