The way my LFM1-EX came boxed was such that the interior box and the exterior box were separated by high density foam inserts which were about a inch thick. The boxes were very heavy duty with about .25 inch thickness each plus styro surrounding the actual sub. All told, the packaging added about three inches to each side of the side and maybe a little more to the top and bottom of the sub. Should easily fit through a standard 32 inch door.
