Re audio SXx 12" 1000W rms 4 ohm dvc


so i went on the website for the subs and found the box should be tuned to 33hz which i have no idea how to do (problem 1). the optimal space is 2.0 ft^3 per chamber. is that before or after displacement of the sub? (problem 2) the rough dimensions that i got for the box are 31.75W x 20H x 11.75 D. that was with a "golden rule tool". is there some calculator or something that can build me a virtual box? i know i need a spec box for these subs but it's a little over my head, any feedback or comments would be greatly appreciated.

It is not accurate though.

thanks, can i use it to make a single port box but still use two subs? or does the box need to be dual chambered with separate ports?

You only have 3.3ft3 of available space after wood displacement but that is before sub(s)/port. In short, you do not have enough available space for two.

well im going to make a bigger box, i messed around with the dimensions and have about 4.1 ft^3 after port displacement. their optimal space is 2.0 ft^3 per so that should work right? to avoid the sub displacement i'll just do a reverse mount or increase the box size just a bit
