Ext. Cab Box Design: 2.5 cuft @ 34hz (2 12" Alpine Type R's)
Here is a design requested by kfx450r. The box turned out to be 2.65 cubic feet (per chamber) after all displacements, tuned to 35.3 hz. There are 72.5 cubic inches of port. I made this one pretty quickly, so anyone is welcome to chime in with improvements/comments.
Final Dimensions are:
T 18 1/4"
Start off by constructing the base, sides, back, double baffle, and the ports, in that order.
You should make these double baffles before you put the port in. Sorry about the confusing order of these pics. Simply mark an "x" from corner to corner to get the center of the baffles. Make sure to get these cuts and the ports very precise. Also, "diameter" should read "radius."
Finally, make sure the box is nice and sealed, then attach the front.
If you use this, post a build log for me, please!
