The Biggest Subwoofer In The World
Source: Bobby Owsinski
There's absurd and then there's ABSURD! and this 6 foot subwoofer falls into the later category. It's actually a project for the UW-Madison Engineering Expo by a couple of Phd electronic and mechanical engineering students. They call it a "bass cannon" and it's said to cause loss of bowel control all over the building it's located in when it operates.
The speaker itself is 6 foot and made of two sheets of polycarbonate riveted together to form the cone, the voice coil is built around a fiberglass frame, and the magnetics are secured by 10 inch steel pipe. The cabinet is 8 foot by 8 foot by 2 foot, and the sub's peak electrical draw is 6kw. Oh, and it reproduces as low as 5Hz.
The video doesn't do it justice, but then how could it? But it's better than wearing rubber pants and seeing it in action in person.
