Box check

[vetkilr01]

Most box's you see slam with two 12's have close to these specs:

3.5 - 4 cubes of air space

One 6" aero port or 40-60 square inches of port

Tuned between 30-35 hz, I prefer 32 hz myself

This is my new box being made:

Specs are 3.7 cubes after displacement (34 W x 15.25 H x 20 D), One 6" aero, tuned to 32-33hz.

one 6" aero is pretty small for even 3.5 cubes. i had two 6"s in mine.

I can get the net vol up but im having trouble getting the tuning down while keeping the port area between 13-16

Your box is too small with those dimensions and only 1 6" aero, it would have to be 18" long to be tuned to 34hz and you box would only have 2.87 cubes without any extra bracing in it and only one double baffle.

If you only add 2 more inches of depth your problems would be over...you would have 3.4 cubes and it would be alot easier, you could Double baffle and brace properly.

Your sub woofer displacement is off. You have two subs so total displacement would be .32 not .16. You also have no Double baffle or bracing accounted for.
