Illuminati (33rd Degree)

Your results look good, and you could expect a nice little subwoofer from that 1ft³ box. It isn't very large and yet has 35Hz f3 and 22Hz f10. Port area is 12in², so you can make it 3.5" square and 5" long.

That woofer is suitable in tiny little boxes from 0.5ft³ up to about 3ft³. Helmholtz frequency should be 20-25Hz.

I'd probably put it in a box between 1ft³ and 2ft³ with Helmholtz frequency of 22Hz. It will work well in cabinets that size range.
