[QUOTE="audioholic, post: 5293441, member: 549629"] Its more difficult, but certainly doable. The hardest part is getting an accurate measurement of what your internal volume will end up being after port displacement, as this affects port geometry for tuning purposes. I believe most people just glass the box to the approx size they require (4cubes + displacement for the xxx15 for example), measure the actual size once completed (using styrofoam shipping popcorn or similar methods) and then alter the length of the port to adjust for any alterations between projected box size and actual box size. Presto, ported fiberglass box with a unique and custom shape. [/QUOTE]
