Dave,
I see they work well for frequencies and amplitudes that can't come in the door. They will probably work just as well for not letting frequencies and amplitudes out that same door. So what about all those resonances that are generated within a loudspeaker where do those go? They probably linger way to long . I bet there will be a loss of acoustic air from the smaller drivers and the resulting spectral change will give you the false impression of more bass..as in other similar devices.
Good luck to you Dave.
