comments welcome, going to FG the rear of the box and the front of the box.
Right now I have made my rings at 16 " , I will cut the 11 1/4 " cutout for the sub in the bottom ring with the dato cuts, then I plan to step cut the other 2 rings, Fill the steps in with FG, except for a 1/4 lip I will leave on the top #3 ring which I will use to mount a custom speaker grill I have plans in my head for.
Probably going to use some expended steel, sand blast and powder coat it, then have a custom polished aluminum retaining ring made to hold the grill in place.
This box will be ported when im done, I am aiming for 2.5 Cubes after displacments, I plan on fabricating a Interchangable port system for it.
The box will house 1 12" Fi Q w/ BP power option
