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?
