i'm sorry that you are a little disappointed there. the drivers just have really weak motors and can't push against the air pressure of a small sub.

if they are going in a car, it might be ok because of the huge cabin gain that you will get.

it would.

also going to a sealed design would help even more.

if you go with 6 cubic feet for each cab and run a total of 1200 watts, you will be shooting just over xmax by a few mm, which is ok.

they will not have that big hump and should get you over full reference spl in room. room gain starts kicking in for a medium room around 25-30hz, so the real response will be much flatter than the model. ignore everything over 80hz.

440
