I tried checking out WinId and didn't have a whole lot of luck making heads or tails out of it. I was gonna have a local shop here make a custom box but they start at $250 for a bare bones box. Anyone who is good at the program mind giving me some numbers? I am looking at building a single ported box for a SD2-12. The fixed outside measurements are 32" wide x 15" tall with the depth being the variable. Figured lower 30s tuning, not sure what difference + or- a few hz would make so up for whatever. Below are the manufacturers specs. If anyone runs these numbers for me, you'll be my hero and I'll name something after you.
