| Re: DIY Bass Trap....Will it Work ?
Hi Scott ,
I'm hoping this explanation helps ...
Membrane bass traps , as per Ethan , rely on the front membrane vibrating , and that vibration being damped in the sealed airgap behind it ....
In the case of a concrete tube , this vibration will be minimal ... for two reasons .
Firstly , be as dense as it is , concrete will vibrate very little ( compared to say plywood ) ...
And , secondly , being of circular shape , it is far less able to flex ...
In a way , the face of a membrane trap behaves as a piston ... Curved concrete couldn't do that .....
My thoughts on Mellencamp's use was that is was an attempt at sound isolation , not absorption ... and the interest in such devices probably a confusion between the principles of a porous absorber ( which a 'tube trap' is .... ) and a membrane trap .... based on shape ...
However , they would make great speaker stands ....
Cheers ,
Evan .
