"As chief designer for Legacy, I work with some of the finest driver fabricators in the world. I also have an open door policy regarding submission of samples from manufacturers. When we select a driver it must meet our stringent criteria of high efficiency and high power handling for dynamic reasons, smooth frequency response for lowest coloration, and well designed motor structure for inherently low distortion. "
Above are a small sampling of the drivers Bill Dudleston and team has tested before making design choices. Diaphragm materials tested over the years have ranged from titanium, beryllium, polyproplylene, ceramic, Kevlar, aluminum, magnesium, graphite, carbonized paper, woven blends, and linen, to silk, mylar, and Kapton.
