a box that deep is gonna be peaky. you COULD mount the sub and port on the right side of that box and do better.

That is a perfect example of "install dependant". If all you needed was certain equipment, everyone would have it, it would all be loud, and it would sound good doing it.

but see the only differnce is the box. i tried making a box that is the same cube, but i wanna try and make it the same shape also.
