This is going to be a build for one of my buddies but i will be making the box. Its for 2 sundown sa-12s and he will using a sundown 1200d. The box is 3 cubic ft tuned to 34Hz with 48 sq inches of port. Heres a pic of the box in sketch up. Let me know what yall think.
I think im gona try a kerf port on this one. Ive never done but ive always wanted to. Ill draw it up and show yall.
Im not exactly sure how. I know that you make a bunch of cuts where you want the round curve to be and you make the cuts like 5/8" deep. The more you make, the easier it is to bend it. Ill c if i can find a tutorial for you.
