Designed to have the best acoustics, this box has beauty as well as function. The dome shape allows for the best sound which can't be achieved through traditional methods used to build fiberglass enclosures. We wanted to design something that nobody has seen before, and with this design we are able to build the box without weighing it down despite it's size (40.5 inches wide by 14 inches tall by 19 inches deep.) With 2.5 total cubic feet of air space, this box is very universal for any 12 in sub you can get your hands on; and with it's acoustics you are guaranteed to get the best sound.
