Hey all I have read about Bass traps and Tube bass traps have interested me as they would be easiest to place being self standing and all.


This artical http://www.diy-home-theater-design.c...rap-build.html outlined a fairly simple solution Capping a concrete tube on both ends and filling with sand.


However the sand part got to me, is sand suitable to preform the basic function of a bass trap? Thanks.

I love the part about, "you may want to tune the bass trap later by adding or removing sand."

Sand Bass Traps

Hey all I have read about Bass traps and Tube bass traps have interested me as they would be easiest to place being self standing and all.

I just made some and they work quite well! Dale Pitcher from Intuitive Design and Mosaic and I spent about 3 hours adding sand in all areas of resonance my showroom. The results were very impressive, probably an eight fold improvement in the sound of the system. I didn't take room measurements before and after, but the room sounds so much better.

We basically followed the steps in the blog that Dale had written.

Its funny, there is not much written on this out there, but most of the critics of this technique all happen to sell acoustic treatments.

Yes, I sell acoustic treatment, but I know a little about acoustics anyway. :D

Seriously, I wish you had measured before and after, because then you'd know for sure what changed and by how much. You'd also have proof to share with us rather than merely "anecdotal evidence" which is far less compelling. (Think about all the praise you read for speaker wire elevators and replacement power cords.)

In any case, I can tell you for absolute certain that a sand-filled tube is not an absorber. It might have some effect on a room's acoustics, but certainly not very much. And it's certainly not as effective as an actual bass trap.
