A custom one tailored to your space available and the woofers you have.

I think the type r driver displacement is 0.17 so

Had mine in 1.75cft sealed each and sounded pretty good. Did a 141 with them sealed, lol! They say you get louder with ported, which I never did try. I say if you go ported then a nice 5 plus cft box at 32hz should suffice.
