box...wat cuft is this?

i just got a subzone box H12D...(sealed)

dual 12" ... and I want to put 2 infinity 1232ws...

but I don't know wat cuft each chamber is...

the box dimension is

Length: 29.5"
Height: 14"
Depth: 14"

My friend did the calculation for me, and he said it's 1.37...

I want to go with wat infinity recommend...which is 1.25cuft...

anyone got an idea?


OH, and what effect does the box do?? more space louder???

and wat if the box is small?

I believe that is 3.35cuft. Also, the are those external measurements or internal?
Here are some that are 1.25:
12x12x15
13x13x13 (1.27)
11x14x14

The formula for inches is (length x width x height)/12/12/12

internal dimension is...

height: 13.5"
depth: 13.5"
length: 14"

so i guess it's 1.47? 1.48?

hmm...

making the box big makes it loud???

and small makes it less loud?

Something's wrong with your measurements, it can't have a 14" external height and a 13.5" internal height unless it has 1/4" wood, which would be terrible. Measure again and then we can help you.

A bigger box will be more sensitive but will not be louder, basically it will get louder on less power, but it will hit its limits on less power as well, the max spl will be the same (unless you're comparing it to a tiny sealed box that has a FR peak, then the small box will be louder at that frequency). A larger box will also have a better low end.
