all drivers, especially those with a cone have "dipole" radiation patterns. If the cone moves forward to make sound, it must move rearward to return to its resting position, thus producing sound rearward also, out of phase with the front wave and therefore dipole in radiation pattern.  The back wave is considered "a problem to deal with" in a box speaker(how to absorb-acoustic suspension) or how to put it to work - bass reflex.  And the back wave is considered a benefit in an open baffle - just let it fly..!!!

I have not heard of this company.  I do have experience with and own Hawthorne Audio Augie's which I operate in "dipole" fashion in open baffles - best bass I've ever had - quantity is not an issue either.  And they cost less than the Acoustic Elegance models.....
