Need Fi Q design

[gmg530 0]

I have a Fi Q12 in 2.5 cubes tuned to 32Hz. I dont like the way the box was made so im gonna make a new one with left over MDF. I have max demensions of 38 wide, 14 height, and 14 depth. i still wanna tune it to 32Hz but in a smaller enclosure like 2.1-2.25 cubes. So any plans will help. Need 12-16 square inches of vent area per cubic foot of volume. also what difference would there be in a smaller box?

I can't imagine that you'll be able to hear any real difference. There would be if you had a mic testing the response but your ears shouldn't be able to tell.

How much port area right now?

Is the goal better daily sound, or higher metered SPL?

What do you not like about what you have right now?

Not sure about the port area. all i know is its 2.5 in wide and L shaped.

I am going for daily driver with SQ but can get loud.

My cousin built it and all pieces dont align very well, glue everywhere, and the MDF is starting to split. (how do you get it not to split?) I rather just start fresh and make it alittle smaller and get the extra trunk space. It is going in a Nissan Pathfinder.

you have to predrill the holes for the screws.

I use an 18 ga air nailer, build up three sides, then go back to predrill and screw. Then I add a piece at a time using the air nailer to hold it in place so I can predrill and screw.

I will draw something up in the morning and post it.
