Only problem I see is soundwaves don't travel in a circular motion, if I'm not mistaken.
Edit- Now that I re-read it, I can see some truth to the supposed theory. Come to think of it, I believe that is what the guys in the UK and Brazil do similar in the Pandas. I would imagine to get the perfect circular air movement would require undefined testing and experimenting. The sub correlation could be a conflict when the air movement would come into contact with that part. Seeing as the air would be moving in one direction while the woofer was moving another.
There could be a simple way to 1/10th scale testing I would imagine. Water in place of air in a controled environment, or compressed air with dust particles or slight amount of liquid.
