Best option for 4.5" driver / 42Hz -3dB / 13 x 15 room / 70dB

10.5H x 5"W x 8.5D internal = 7.3 litres.

How do you fit a driver with a 6.5” bezel on a 5” baffle? That is going tpo be REALLY tight to the edges of the box and you will hear that. Is the inside of the cut-out beveled? (there will be little or no room for that on the sides. That is going to be an issue. Early reflections off the sides.
