port area per foot?

[Davidd92]

I could but I wouldnt know how to do that unless someone came up with a box plan for me.

So would the box plan I have work well? or do you guys think I need more port area per foot?

[matt402]

sounds like a good design to me.

i had 21"/cube for an XL 18 & it could move some air .

[Davidd92]

Well I want to be able to throw a decent amount of power on it daily and be fine. Will the amount of port area per foot work for 2500rms+ or will i need more in the 18sqin range?

Can someone come up with a cut sheet for this box plan

box

Height 14.5"

Width 31"

Depth 18"

port

height 13"

width 3.25"

length 32.5"

should come out to 2.5cuft at 34hz, 16.97in2 per cuft (42.25sqin)

thanks

It comes up with some weird numbers though. Like the back and front are the same size even though theres a port, and the port sizes arent there. So I just wanted someone to help me out with the cut sheet so I dont screw it up.

You really can't do math and figure out where stuff overlaps and doesn't? I mean that's just laziness...

[cthedinger]

16-20 sq in per cube preferably 20 sq in per cube

[Davidd92]

Sorry I wasnt exactly paying attention to how it says to cut it. The front it wants me to actually cut out the port. I dont have any tool to cut that cleanly. So I tweaked the sizes so I wouldnt have to.

Bottom/top 31x18

left 17.25x13

right 16.5x13

back 31x13

front 27x13

and for the port I came up with 13.25x13 and 13x13

This will work the same correct?

I'm going to start building this box either today or tommorow. What kind of glue seems to work better, liquidnails or titebond?
