1. ## I can't do it :(

A friend asked my for some help with his box design, and i just realize my math skills are long gone. I feel dumber than a 3th grade student

don't worry, i never had drawing skill either

JBL recommand 2.25 ft/cu but the dimension in the pic are more important. The tuning can be anything between 30-34hz. The bottom angle (not the right one) must be 68degre. I just can't calcul anything, would a good samarian help me?

ygpm

Well if i could only know the top sheet dimension (the 68 degree 3th grade calcul), I should be fine with the rest

You might as well just go ahead and do the whole box. I think. It's going to be a pita getting a port with a reasonable amount of area in that box(the 68 degrees makes things a little harder)......if you don't I might.
