What software to use??

[Torres]

it's for as many subs as you want. just gotta make sure the dimensions for the box you put in gives enough airspace for the amount of subs you have.

So your box calculator is for this type of box

Or will it work for this

[Torres]

it will work for both. the second picture is still considered a slot port. you just have to know where you want to put the port. and if the port bends, that the height gets divided in half. so in that example, if that first box had its port in the middle, it'd go down from 2.5" in the middle, and split to 1.25" across the back wall

Which is better or does it really matter

[Torres]

more so preference, tho it still will vary from install to install. and some will say you could get phasing issues with one sub close to the port, and one sub further away from the port. only time i would see it mattering is if the port is in the middle and is too thin when it splits. then it'd be better to keep it as one solid port the whole way through. but i have heard of very good results with the port in the middle. tho they were in bigger installs with sub up and port back

would sub up and port back work in a car too?? Because I was thinking about doing that but how would I do the port..just a square port?

[Torres]

depends on the car. i'm not toooo familiar with trunk cars. i do believe facing subs in the cabin from the seats sealed from the trunk is one of the loudest ways. andym85 had a pair of 10's like that and it sounded damn good. not to mention practically no rattling. anytime the port shares a side of a box, it's a slot port. the only time you shouldnt check that box is if it has 4 independent sides

How would you port this box? http://www.stevemeadedesigns.com/board/ind...st&p=868380 tune to 30 hz

So something like this..is there anything special I need to do in the box..do I need to put a seperator in the middle or just leave it open

[Torres]

i'd leave it open. and from the looks of it, that port is too small. unless that's not built to scale
