Sub boxes are being cut this weekend. I wanted to double check some ideas, but time is a little crunched.

22"wide x 23" tall x 20" deep with a double baffle is 4.5 cu ft before bracing. So I'm guessing around 4.25 cu ft net which seems like a very common size.

What do you think about the 20" depth? Is that okay? If it is, then I can use the same sides for multiple boxes.

17.5" or 18" wide x 23" x 20" will get around 3.5 or 3.6 before bracing. That could be used for sealed 15's or porting one of the 12" Daytons or the 12" Titanic.

Anyone see any problem with a 20" deep box for the common 18" sub drivers?
