RE: Tube Bass Traps.
Posted by Markeneret on December 17, 2016 at 09:18:43:
The ends are made from 1/2" pressboard= low resonance, many speakers are made of this (don't get it wet!). The white PVC is attached with white upholstery tacks to the outside of this circle of pressboard, so the bottom of another trap (with no PVC on the bottom) fits neatly into it. NOTE: I cut these circles by hand with a drummel tool and compass. This was a pain. I would pay someone with a band saw to cut these. I don't recall the thickness of the diffuse plastic, but I did experiment with about 3 sizes. It was medium-sized, if that helps. Not a tarp.
