the unit is inch on this pic

 

4.03cu" if those are the measurements from the inside of the box :thumbup:

 

it's from the outside of the box. if 1 cub. ft is recommended for one 12" sub, for two 12" the size should be double, correct?

 

i got around 3.8cf....yes double the size for 2 subs. dont forget the baffle in the middle.

 

this is the box the sales wanted to sell me.. too big for 2 subs if the recommended size is 1 cub ft.

 

oh yeah Cashis, how did you calculate that out?

 

im not cashis but....i forgot about the triangle first...so to find area...base X height X width.

12*15*32=5760

then find out the triangle:

5*15*32=2400/2=1200

add those two numbers... 5760+1200= 6960 cubic inches.

convert that to cubic feet by 1728 (12*12*12). which is 4.03 cf.

oppps my bad on my first number.

anyway...the box is too big either way.

 

ur formula looks weird
isn't this the formula for trapeoid, (top+base)heigh/2 and for volume in this case, we times the above number by 32?

so it's like (12+17)15/2 and then convert that to cub ft? i just don't know how to convert it

 

opps same number as 6960...but well it's too big

is there any genetic box that is 2 cub ft or it got to be custom?

 

can you make it yourself? thatll be best IMO..

but im sure QLogic makes a box around 2 CF.
