DIY Basstraps project

[F5D]

This is how I just spent my summer holiday...

I finally decided to build my own bass traps after I found out how much it would cost to order proper bass traps from USA.

The biggest problem was to find proper wool for the traps. Because I live in Finland, the choice was Paroc rock wool. I chose FPS14 wool (66kg/m^3) which should be good enough for bass absorption. I bought 20 pieces (1200x600x50 mm) of the wool which was enough for building 4 corner traps and 3 basic flat traps (2x 6" thick and 1x 4" thick).

I used polyester cotton and felting to avoid rock wool dust and fibers from escaping the traps. The traps were finally coated with simple white fabric.

I decided to post some pictures of the project so here they are (only 4 pics per post was allowed):

I have not yet tested these in action. I will move to a new apartment in August and will install the traps there among other acoustic panels. I will report then how they work.
