I need to build some speaker enclosures for my LC80i's. I saw the dimensions on the polk website but these dimensions won't work in the available space. Does anyone have a different dimension box? I am not sure how to figure the cubic space. Do you multiply the three dimensions listed on the Polk site and divide the total by 12 to get the space? Or can I take a few inches off the height and add it to the width?
