Update...

Haven't had much time to build the box, but I've had time to measure up and plan.

Without the tool tray I can build 1 CuFt box and full Grill Cover.

1 CuFt Box is average size volume for a Single 12" Woofer.

With tool tray in place. Box will be roughly 0.7-0.8 CuFt with Full Grill Cover.

This would suit a Single 10" Woofer.

What style of box would you guys prefer?

Thanks
