I ran across this article about a 60 inch subwoofer. What kind of bass traps would you need for this thing?

How about the one in "Back to the Future"?

Mark, very cool pix. Man would I love to be sitting on that couch listening to my tunes...
Back in 1959 Electro Voice introduced a 30 inch woofer. I have the specs and cabinet plans at home, the volume about the size of a small bathroom.
Can I combine the 10 ten-inch drivers on my SW800's and count it as 100 inches? ;-)
You think that's big? Check this thing out. You have to scroll down a little.
If it costs less than a Bobcat bulldozer, I will buy one. I need to find an entertaining way to demolish my shed while throwing a pool party. ;-)
