Hey, all!
Not sure how to Google this business so I figured I'd just come out and ask!
I'm setting up a new space and I'm trying to reuse some stuff I've built already rather than tearing it all apart and starting over.
Which is more effective (or maybe they're the same):
A) one panel with 6" of absorption
B) two panels with 3" of absorption each stacked on top of each other (but will have a 3" air gap between the panels).
Trying to figure out if it's worth my time or happiness quotient to rebuild some of my pieces of absorption.
Thanks!

What type of insulation? Are the panel backed with something?
Panels or walls with an air gap between them and isolated from each other will perform better.

Single panels spread out held off the wall some will be overall more effective for general absorption than two panels stacked. Two panels stacked will be better for bass absorption, but if the material is too dense, it'll start to be less effective at higher frequency.

Depends what you're trying to do, how much coverage area you have and where/how they're placed. In most cases I doubt there would be a big difference between the two. How dense is the material? Are trying to max out on bass absorption or are you using these as broadband absorption? |

Little more info!
Absorption is happening via Roxul Safe N Sound in a rectangular frame with no backing. The insulation is not compressed; it's at-spec for width/height and it's spray-adhesived to the side walls of the frame to keep it all in place.
Basically, I'm going for broadband with an emphasis on bass trapping. I don't mind a little too dead of a room. It's the control room where I'll also be tracking singers sometimes.
I built eight individual 6'x2'x3" free-standing panels (in addition to a number of other thicker panels) to knock down a bunch of reflections in my current space. I don't need quite that many square feet of coverage in my next space (that I'm in the process of moving into) but I do need some more bass trapping. Sooooo...I figured I'd stack 'em if they'd work well in that 3" insulation, 2"air gap, 3" insulation, air gap, wall configuration.
They're all free standing and will have 5" of air gap between the panel and the wall to accommodate the feet of the panels.

Because there is no backing it should work fine and get you extra absorbtion. It should also get you to a lower frequency. I suggest you test the room with one set then double so you can identify the difference.
If they had backing and you were looking for soundproofing I would be telling you to be carefful with making a triple barrier withe the panels and the walls which performs worse than double.
