6 180w 6×9’s
2 8” Woofers in tuba horn enclosure
2 12” Woofers in vented enclosure, 27hz tune.
2 15” Woofers in vented enclosure, 25hz tune.
This subwoofer is 5 feet square, 1.5 feet tall, is driven by 4 15” sub-woofers, doubles as a large coffee table & quite literally came to me in a dream while I slept.
While I would like to build it one day to see how it sounds, it prolly won’t be anytime soon. This sub has a very low WAR rating. (Wife Approval Rating)
