Need some box sizes, anyone have a sub box calculator.

Heck yeah, I had one of the 10's and it would almost blow me away on its own. But I gave it and my custom built box I made to my dad last year

well you actually have to add port displacement into your equation or your box will be smaller then planned thus raising tuning. IF it was me i would put them in 3.25 cubes each after sub and port displacement tuned to roughly 34hz. they are subs built to play low end music.
