RE: Flare Audio's magic boxes

In airconditioning installations, sometimes long ducts have wide sections (atriums) along them to act as traps for transmitted sound (fan noise, rumble). That's what the labyrinth in your posted pic makes me think of. Could it have an effect in reducing the 'chuffing' of a too-small port?

"what happens large signal?"

A guess: maybe the duct is so narrow / flow resistance is so high that it barely functions when signal is large.

That is: maybe the design works as a ported box at low power, when airspeed in the duct is low (giving a good -3dB value for small signal tests) but acts as a tiny sealed box at high power (giving no bass but lots of power handling with larger signals).

...kind of like the programming on those VW engines :)
