    i was looknig threw that whole post and i went to teh one site

    http://www.diysubwoofers.org/prt/dual_chamber.htm
    IT was very help ful but i didnt know how they figred out all teh calculations so i went on download.com and downloaded TURBOBASS its an old program but you just type in specs that are so easy yo find for your speakers and it tell you what size sealed box, ported box, port length,diameter . Its very helpful i encouraged everyone trying to make there own boxes to get it.

    If designed, tuned and built properly to the T/S Parameters of the subwoofer this enclosure will have EXCELLENT SQ; it will go as loud or louder than a standard vented (depending on the sub) and have the deep low bass extension of a sealed enclosure.

    basically all you do is build a ported box. but you also add another section to it that is ported at a different fq inside the box and then port it out of the box. its really quite simple once you get the concept of a ported box down.

    calm down there buddy their are other posts about this and you could go to a car audio forum. but it is 2/3 of the box for the sub side and 1/3 for the other side.

    It's not quite that easy...

    First find the maximum usable vented volume for the subwoofer in question. You may have to ask places like TermPro or even the manufacturer itself (do not use the printed volume as max...they are greatly downsized). If it is too big for your use, reduce it some.

    Now take this volume and model a box in WinISD using your sub, the max (usable) vented volume and model it with 2 vents (even though you have a third one), tuned low...my 15" ABC is tuned for about 28Hz.

    Now decide how you will build your vents...either slot vents using MDF or PVC.

    Here is where the tricky part comes in. You have to figure out the volume your vents will displace and then add in over all size to the box to compensate for that to get you back to your original volume. Remember you have 3 vents that have to have displacement factored in AS WELL AS the subwoofer AND the chamber divider. It can get a bit hairy but take your time and patience and you will figure it out.

    Now, split this final volume into 2/3 1/3 (divide by 3 and then double one side)

    And build...remember to add your 3rd vent between the 2 chambers at 1/2 way on the vent for optimum flow.
