so i was planning to build a box for my new platform 3HP 12 and i went off of the 12.5 In. Sq per cu. ft but then my friend told me that the port area was to small do you have any recommendations for the port area that this subwoofer requires ? I wanted to run the full 3000 rms watts using my Crescendo BC 4k
box size is 2.5 Cu Ft to be used just need help with the port and then I can adjust my dimensions from there wanted to tune to 28hz
because that is what I told Dave the box will be tuned to
any help is appreciated.
