Really Need More Information. I Suppose This Is An 18" Judging By Box Size. You Need To Double Baffle The End Where The Woofer Will Be Mounted, I'd Probably Add Bracing In The Corners. 12-16sq. in. Of Port Area Per Cubic Feet, Tune Around 30hz-35hz. You'll Have To Calculate Your Dimensions To Determine Your Port. A 2X4 In The Middle As A Brace Wouldn't Hurt, Either.

ok, made a newer design, cant post pics but its about 7 cubic feet. and its got about 110 square inches of port area. the port is accross the bottom and the sub area is above it.
