this one here
The guide is not overly user friendly and polk does not give the length of each chamber, they give the volume, which is no good to me.
The box is supposed to be 35 1/2 inches in width 17 inches in length and 16 inches in height.
Accounting for the width of the 3/4 inch MDF, I would like to know if someone can figure out the length of each chamber, so I can start on the box blueprints.
I also am aware that there are 3 vents, 4 inches in diameter and 9 inches in length. however from the reference image given by polk the chambers appear to be staggered. Is this correct procedure ?
I would appreciate any help because this would be my first custom box build.
