I´m going to build relatively compact/low/loud cab, I´will have to make quite a few compromises but still sure the cab will end up superior to most wide avilable, mid priced 1x15 or 2x10´s.
Winisd says (2.83cuft tuned at 47 hz): f3@50 hz, f10@36 hz, mech. limit 293W@80hz with slight (1.6db) upper bass bump centered around 100hz. I tend to add some eq in that region anyway so its not much of a problem.
I´m planing to cross it over somewhere in 1-1.2 khz region, just before the beaming on 15 kicks in to get more of a ´bass cab´ voicing, 2nd order butterworth, both lpf and hpf.
These days I´m gonna be hunting some decent 1/2 plywood, wish me luck!

You can get away with using light 1/2 inch ply if you brace it very well.

I built a 4.0cuft box with just a single 15 plus ports, and I have little wood left in the baffle. Just askin'.
