if that port is only 16 inches on each side......and assuming 3/4 MDF, your box is 4.17 cubes per sub @ 44.97 HZ factoring in End correction.

thats ridiculous btw.

 

[talon2nr7588 10+ year member]

the ports are 19.5" x 16" x 3.5".

OK FORGET THE FIRST POST!

i made up a new design.

the new box is 40.5"x20"x23"(internal dimensions) with a 3/4" divider in the middle. that is 5.29 gross cu.ft. per sub. this what i came up with. the port will be 3.5"x20"x20.5". will this tune it to 35 HZ?

 

[talon2nr7588 10+ year member]

each sub will have it's own port

 

[iamamp3pimp 5,000+ posts]

does that port have an L?

i hope so....

 

[iamamp3pimp 5,000+ posts]

In short, no. its still gonna be over 40 HZ.

Hey Man,

Still aint got it in? Sorry about your missfortune with that first one not fitting. use this

Seance you got a divider, just go to the bottom and figure it out for 1 sub and 1 box, then make the other side of the divider the same. Enter you box volume, your wanted port size (as in the port area(H X W)) and the desired freq.

Using 5.3 ft cu. and a port 3.5 wide by 20 tall, I get 20.5 long as well for 35Hz, dont see whats wrong

on carstereo.com port calc i typed in 5.29 cu.ft, tuned to 35 hz, the width is 3.5", and the height is 20", and it said is had to be 20.46" in length. i rounded to 20.5".

i clicked that i wanted a slot port and square.
