Posted May 21, 201015 yr Can anybody tell me how much of the port length I need to get rid of in order for this box to be tuned to 32hz?Sound Solutions Audio - 15" XCON Optimal Ported EnclosurePlease and thanks!
May 21, 201015 yr Author I wish I could help you man but I cant so ill help to get this thread answered. Can't download the sketchup file. Unreliable Technology FTW.
May 21, 201015 yr Just rough math .... 30hz tuning looks to be 31.125" length. If you want 32hz you will need roughly 29" so take off 1.25"

May 21, 201015 yr cannot find 1" MDF... Sure you can, two sheets of .5" laminated together will work! ....

May 21, 201015 yr Not bad at all! Once you double baffle it will be fine. If you feel you need more bracing you could add threaded rod or wood dowels without taking up much internal volume.
May 22, 201015 yr That design only calls for 3/4". And your going to need to take off more then 1" of port length to raise the tuning to 32hz. From my rough calculations it should be more like 6.75" of port length taken away. Which would put the box at 4.26ft^3 @ 31.86hz.

Where would you find some threaded rods/ wood dowels? Home Depot/ Lowe's? If so how much do they cost? How would i go about calculating the volume displaced by them?Thanks
May 22, 201015 yr Yeah lowes or HD will have it. YOu can also use some scraps of MDF from your box build. YOu want to tie the top to the bottom and the front to the back.Edit to add if you use scrap MDF make sure to round the corners. All the way to the bottom right above the pic of the T-Nut.Brace volume calculator
