bassl0va Posted August 29, 2010 Report Share Posted August 29, 2010 I fixed a DUB 10" and built it a 2.4 cube (far to big lol. Gonna put two 10"s in it later) tuned to 19hz. It played mean low but didn't really use the power to the best of its abilities. So I shortened the ports (not sure of the tuning now, about 30hz maybe. Much louder and lots of room for more power. Although there is some port noise at <20hz you can't hear it over music/movie effects and this could be fixed with flares on the ports. Also as there is more headroom it can now be tuned to give better response at lower frequencies. Moral of the story, experiment.
