Ethan, John (and of course, anyone else who has an opinion ;-)
I seem to have read some conflicting views between you guys on your opinion of panel absorbers. Over on the Recording Studio Design forum (which is linked here often), I came across this post, challenging the effectiveness of panel absorbers:
_______________________________
The data that never seems to get mentioned with respect to absorbers is their absorption coefficient (efficiency) in their respective bandwidth. Of course, you can build a panel absorber with whatever resonant frequency you like. 10Hz? No problem! But in order to do this you need a very massive panel. Massive panels have more inertia and are, therefore, more difficult to excite. More difficult to excite translates to less efficient. The only way to make a highly efficient panel absorber is to use a very light panel in conjunction with a very deep cavity. In other words you need a lot of space.
There's no getting around it. If you want to absorb low frequencies, you need space. Absorbent hangers just help maximize the efficiency of a given space

Now, I'm no expert. In fact, I don't have 1% of the expertise of Ethan, John, or others on this board. So I've reserved judgement. I'm just curious to hear the opinion of those in the know on this board.
Thanks!
