i have a problem. in my zeal to brace the out of the box ... i ended up doubling the walls instead of bracing the walls ... now i have a net volume of 3.05 cubic feet instead of the targetted 3.5 cubes. (drivers included assuming .1 and .15 volume displacement of the two drivers)
on the weight side of things:
enclosure weight is 99lbs. + 59lbs active driver + 12lbs.
PR + steel weights 44lbs.
