In the past few months, easily adding up to more than a year I was busy figuring out how to build the JR Superwoofer.
The basic shape of this Superwoofer is a round tube. How on earth does anyone like me without any skills in constructing build a tube?
Well after much browsing around the internet I came across this site. http://www.facstaff.bucknell.edu/esantane/movies/sub.html
These so called sonotubes (see here http://sonotube.com/products.aspx for their website) are used in constructing to act as mold for concrete pillars, for bridges etc.
After much browsing the internet again, I found that these sonotubes were also available in the Netherlands (at http://www.hakron.nl/) And they were kind enough to sell me for a small price (40 euro) a tube.
Making it the right size and gluing several layers togheter was the next step.
A picture of the tube can be seen here.
The next challenge was the top-lid and bottom. The pictures I had found on the internet and those I mailed during the preparation gave me no clue how the internals would look like.
Fortunately, very recently, I found pictures on the AudioKarma forum (http://www.audiokarma.org/forums/showthread.php?t=646067) showing the top and bottom part of the Superwoofer.
