RE: "But it's physically impossible to have more sabins of absorption than the surface area of a device."

Good point David. In the case of a Helmholtz resonator, the turbulence at the mouth is very high. At least I think turbulence is the right word. I'm not a physicist, I only pretend to be one on the Internet.

So the net effect is sort of like a horn loudspeaker, where the horn is an impedance transformer. Or like a megaphone that "passively amplifies" (there's an oxymoron for you) by restricting the frequency response.
