Also very interested in learning more. This is a big sub, bigger than i guestimated based on the cone size and photos. From Gary's Technical Specs on his website:
SuperSub (optional): H 41” x W 26” x D 38”
This makes its footprint 82% bigger than an XLF!
Hi Lloyd, It is a BIG subwoofer. In addition to that footprint, it also has a 3-chassis ServoBass amplifier. The sub weighs about 195lbs and then add another 70lbs for the amplifiers.
