One of my patrons over on Patreon wanted some help with a box design.
He is trying to fit a 12" subwoofer in the middle of the floorboard of
his crew cab pickup truck. For the driver we are using Dayton Audio Reference High Output 12" subwoofer.
The enclosure is 2.5 cubic feet and tuned to 32 HZ. For the port we
went with a 2" by 19.5" slot port that is 36 1/4" long. The f3 is 28
HZ. Here are the frequency response and cone excursion plots from WINisd.
Frequency Response Ported (Green) vs Sealed (Blue)
Cone Excursion Ported (Green) vs Sealed (Blue)
For more information on how these were modeled in WINisd give this video a look:
If you would to build the box for yourself the you should be able to piece it together with the dimensions in these in these pictures.
