Screwed up new box.

[mackin13 10+ year member]

Just finished my new box, and i kind of winged the design and thought i knew how to do it by myself. Wrong:

Box sucks, only hits real low. Not sure what i did wrong, some one help me out.

Driver: Massive Audio CW12

Box i built: 3.07 ft^3

port: 16x3x34.75

Heres a quick sketch i did. I would like to retain the boxes outline, maybe cut off some of the width on the far right to make it a little bit smaller.

I want my new box to be 2.5 cubes at around 30-33 hz?

That box in the far left needs to be chopped off. Its messing with tuning Im sure.

I was afraid of that. The response of the sub now seems to be really weird. So yeah, somthing isnt right.

why do you have that lip there in the top left corner. air will get traped there. if its to fit it into a space leave it there but close it off inside, should see significant difference

Ok, ill seal it off tomorrow. I got a few cans of expanding foam lying around.... That should work right?
