Default 30Hz tapped pipe

Since he has a 30Hz HPF in the amp I gave it a little bump

It appears to be a T-TQWP, like what you built before with the 3015lf's.

The baffle board the driver bolts to splits the inside dimension in half, and the 'end' of that board is the same dimension front, top, back. Everything else is brace.

jbell is right on about the bracing. I used 4" 5" & 6" holes in the drawing as an example.
Here you go:
