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.

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?

Hey Man,
Still aint got it in? Sorry about your missfortune with that first one not fitting. use this
http://www.carstereo.com/help2/Articles.cfm?id=31

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.

yeah thats the website i was using, but iamamp3pimp said that it was wrong.

dont see why he would say that... its just a calulator with the same formula every other program on earth uses. If you really wanted to you could use WinISD and get the T/S specs off kickers sight to enter your own sub. But I say go for what you said. So long as you are entering the right information in that web page its close enough. But if 5.29 already takes into account the port displacement and woofer displacement then you should be fine.

so the other box wouldnt fit and this one is bigger and is going to?

talon2nr7588

yeah this one is a little bigger. the other one was 35.25"x22.5"x29.25" with wood.
the 29.25" was too long for my trunk, so i just reshaped it. this one will be 42"x21.5"x24.5" with wood
