DIY Bass Trap

For instructions, go to
http://forums.anandtech.com/showthread.php?t=327056

That thread includes information about materials used, where to buy, how to make a backer frame, how to fold the corners, etc.

I will eventually be posting frequency sweeps of before and after results, including the before and after results of Audyssey MultEQ XT.

*Disclaimer*
Attempt this project at your own risk.
I'm not very skilled at DIY stuff, so this is a pretty easy project, but there is the potential for harming yourself with the necessary tools and materials.

Any questions? Reply in the Anandtech thread mentioned above, or in this video I suppose.

703 is mineral wool. Wool made out of glass or stone fibres is called "mineral wool". And that is probably why you are wearing a face mask when making them :)

@Detvanliga

You're saying rigid fiberglass and mineral wool are synonymous?

I specifically chose fabric with a tight enough weave to keep fibers in. Had I used burlap or something, that would be much more likely to leak fibers.

If you're worried about it, you can put another layer (like cotton batting) between the absorption material and the covering.

A) This is not a bass trap but a broadband sound absorber and B) a layer of cloth will not hold the mineral wool fibers in - when delivered and stored by the hardware store it comes in thick plastic and stays that way when at the store. Usually it is even stored outside the store.

Unprotected mineral wool in your home can cause all sorts of negative side effects.

@Detvanliga

A) Yes, I made sound absorbers in general, but just about every place to buy these broadband sound absorbers that are capable of absorbing bass frequencies are referred to as "bass traps", so I'm following that convention.

B) These are not made of mineral wool.

I bet you didn't think 9,951 people would watch this.

Yes, mineral wool is a "collection name" for fibres made out of glass or stone.

And my point is that when the manufacturer ship it (and the reseller stores it) then they cover it completely in a thick layer of plastic, which is probably the only way to keep the fibres in.

NOT saying you are doing anything wrong, mate, just pointing out that mineral wool might not be something one´d like in one´s listening room, except for when hidden behind plastic or inside a sealed wall.

I'm doing some work on Slim Productions Studio and you have aided in my research. I hope you'll be able to see an improvement on the shows we work on in the future.

Scrim side down in the construction actually means that the scrim will be facing the room when mounted.

From what I understand, the scrim reflects some higher frequencies, so it helps balance out the absorption for the whole room (the scrim traps focus on bass without overdoing higher frequencies).

There are also particular low frequencies that the scrim helps with, not sure why.

This is based off some of the links I have in the linked Anandtech Thread (if you want more info)

@YOyoYOhowsDAjello How does the scrim side down help with the acoustic absorbtion for the bass frecuencies??

@FiSTFigHT09 hey man, i just finished building my studio witj my brother. If you want to see how we sound proofed go to my video's and check out the video i posted. Take care
