HELP!!!! PORTED BOX for two jl 12w3s

[pologolfer1 10+ year member]

Ok guys i am going to build my own box for my 2 jl 12w3s but i am not sure what deminsions i need. Like port size ext. I am looking to make it within 35" wide preferably within 32" wide and no more than 14" tall. On jl's web site they give box plans for only one sub boxes so does the port size change when adding two subs? if anyone could help me with this i would be very thankful.

Thanks in advance,

Jonathan

what are you wanting to tune this to? what kind of port do you want, slot or round? I'll get ya some plans real quick if you can answer these...

Here's a quick run.... 3.5 cubes net, tuned to 32hz, 32" wide by 14" tall per request.... see if this fits ur purpose...

The port width is a little fuzzy.... it says 4.480.... or 4.5"

Yeah a basic program..... however, it is simple enough to round up or down to the nearest equivilent fraction..... 21.123 is easily enough 21.125 or 21 1/8"... a few thousandths is nothing.... for that matter anything you use to measure your cuts is gonna be off more than a few thousandths...

true enough, but to the human eye seeing numbers that specific can be confusing.

to the OP, if youd like i can do a 3D sketchup for ya...
