All of the links I hit embed the same photo of the Asian woman holding up a prototype. I can't find anything on the physics involved. Magnaplaners, ribbons and electrostatic speakers all sound pretty good as they have enough surface area and low mass that the diaphragms don't have to move much. This promotes low distortion. The problem has always been they have to be pretty large to get decent SPL and low frequency response. I use ribbon speakers in my auditorium projects on the front face of the stage lip to give the people in the front two seating rows (high rent district) an audible image that matches the stage rather than the sound that comes from the side array speakers...like the center speaker in a surround system. I'm always looking for more tools to work with. I hope the sound quality matches the hype.
