RE: Tube Bass Traps.

Posted by Markeneret on December 14, 2016 at 09:24:28:
I experimented with a variety of clear plastic thicknesses for the diffusion. Opted for a thinner one than the 2 mil, but I don't recall what I settled on. Have to disagree with leaving the foil on the fiberglass tubes: it's way too thick. The original tube traps use a clear plastic with a number of different holes in it: presumably to absorb / diffuse different frequencies. On my DIY, I used the clear plastic as a solid peace on 1/2 side of the tube.Stapled it to the presseboard-circle ends. It's okay if it flops around the length of the tube. You still want the bass pressure waves to get to the fiberglass. I bought speaker fabric from Joannes fabrics:4 ft wide. Rolled the tube slowly as I stapled the fabric to the pressboard circles on each end. Once the fabric totally encircled the tube, I folded the final 2-3 inches extra fabric under itself, then used fabric-glue along the length to seal it. I ensured that the glued seam was on the NON-diffuse wide of the tube. Also place a brass upholstery tack in the fiberboard circle, on the side of the diffusor (opposite the seam-side). This was done, AFTER affixing the white PVC end to the top only: used with upholstery tacks for that. Remember to leave about 1 inch of the PVC strips extended on the top of the tube, to hold a 2nd tube stacked on top.
