Thanks for the replies. If you wouldn't mind looking at this design I sketched up I'd be much appreciative. Its 11 cubes with a tuning of 32hz, has 215 square inches of port (somewhere around 19 sqin per cubic foot).

I am having issues with choosing a design to use. As stated in the title, the subs are 2 Lvl4xl 18s, they will be powered by 2 IA 20.1s at 1 ohm strapped. First up is a 4th Order. Sealed Chamber = 4.8 Ported Chamber = 12.8 Port Tuning = 50 Port Area = 357 sqin" I've never built/designed a 4th order bandpass before, so I'm kind of hesitant on this design. If the tuning is too high, I figured I'd make some sort of plug that drops the port area to 300 and the tuning to 46. Ported design is pretty standard, 13 cubes tuned to 32 with 210 sqin" of port. What I'm looking to get out of this setup is more of a "low end monster" than anything, but not really sacrificing the upper spectrum of sound (45hz-65hz). If you guys don't mind steering me in the direction of the better enclosure for these speakers, it would be much appreciated. Thanks, Larson

It'll work fine as long as you have the correct amount of air space/port length. I've had several enclosures with ports like this, that all seemed to do fine. Larson

I am pretty sure its "Soul Survivor" by Young Jeezy Feat. Akon. Things looks pretty damn loud by the way, good work! How do you like those IA 40.1?
