Which design to go with

[zdoc 0]

I have an 18" zcon on order so I'm starting the build here in the next couple days. I have two designs worked up and just curios what every one thinks would be better, more so concerning port area. I plan on using either a 10" or 12" round port. Box will be sub up port back in an 06 xterra.

First design: 6.93 cubic ft. after all displacements with A 10" port tuned @ 37 hz port area = 11.38 per cube

Second design: 7.4 cubic ft. after all displacements with a 12" port tuned @ 37 hz port area = 15.28 per cube

Just curious what everyones thoughts are, thanks
