Box design for btl's

[t-rust 0]

I recently just ordered me two 18" fi btl fully loaded and im selling my 18" q's to my buddy. What I need is a good box design for my btl's. My maximum measurements for the btl's box is 49"x20"x29". i currently have aero ports for my q's and im wanting to do a single chamber with a big slot port, subs up port back. And i also need a box design for my buddys setup, max measurements of 40"x26"x26", with the same idea as my box. so if there is anyone with ideas, let me know please. thanks

That is actually a little on the small side for (2) 18" BTLs, but it will work.

A box 49" x 20" x 29" with a 25" wide x 6.5" high x 19.25" long port gives 10.8 ft^3 net volume with a 35 Hz tuning.

That assumes a 1.5" top and 3/4" sides/bottom.

40" x 26" x 26" is even smaller. . .
