Mrtennis, thanks for the vote of confidence but designing and manufacturing an electrostatic element is out of my league. Doing so would call for a level of engineering and financial commitment that is beyond me, and besides at this time I don't see an opportunity for dramatic improvement over what's being done by the electrostatic manufacturers who are already out there. On the other hand, I think there is still substantial room for improvement in cone loudspeakers.
