Actually it is very good association. In Zaratustra amplifier bias was made by the very same concept. It was the Newton's Laws of Motion in action. The similar idea might work in tuning bass horn. We can look even beyond that.

Back in my youth I was studying design of railway locomotives and I remember that they had one devised that highly attracted me – the antivibrator. Let live aside how and why it was used on locomotives and let to apply the same ides to our lightly-made midbass horn. Keep it not as the real pros but rather as brim-attack.

We have 7 light segments of the horn and they resonate, individually and together. In the end of each segment we hard-bolt the Aurasound’s Bass Shakers:

Each Bass Shaker sits begin some EQ, volume control and phase switch. Now we can do with the resonance of out horn whatever we wish… make horn form very cheap and light material… Theoretically, if it works then it open a new whole outlook at the “pain” of midbass horns. BTW, this idea I was playing with while I was thinking about my “Resonant Oops” concept…
