Foam on top of traps!

Question Foam on top of traps!

Hey everybody! I always wonder...We all know that a "regular" acoustic foam (auralex, sonex, sonique,...) are good for high and mid frequencies and that they let through all the bass frequencies. But would it be bad if I used them in front of a thicker trap made with mineral or rockwool for example instead of the cloth material everybody uses just to hide and keep the mineral/rockwool in place?!!?! I have a very thin acoustic foam and I've read about using them a little spaced out from the wall to get a better result, so the idea of filling this extra space with a bass trap "covered" with the foam came to mind. I know there must be a reason for me not finding pictures or data about this, but anyhow...I would appreciate knowing before I make my moves with the foam.
Thanks a lot!

I do that a lot! Most of the times just to make things better looking. The clients seem to like dark grey peaks...

You should look into printing on the panel for your clients if your looking for something SUPER cool looking.

i'm on to my next phase of traps and was thinking of doing this too. i've got some sonex that is less great than auralex, so it's not doing much by itself. however, on top of a broadband absorber could be a different effect altogether! if you were doing 3-4" absorbers, where would these be best placed or utilized?

Go for the corners if wanting to bass trap. They also could be used for early reflection points.

but depending on your room size, you may be better suited to use the foam seperately to get greater surface area of absorbtion. i may be wrong, but foam on top of rigid glass may be a drop in the bucket as opposed to foam next to ridgid glass.

2 cents

It would serve no purpose as the bass trap is already absorbing the higher frequencies as well. Basically it would be an expensive cover.

Yeah, I kind of agree. Though, like Glenn said, you could do it...it wouldn't *hurt* anything. It just wouldn't help all that much either.

I wouldn't glue the foam permanently! Because once the room is treated with bass traps, you start hearing all the small anoying reflections much better! That's the point where the foam comes in handy!

From this SOS article.

I think they look nice....I have some of the same Auralex panels that I picked up cheap some years ago. Now I know better, but they won't get wasted.
