The Scan-Speak D3004/6600.00 builds on the experience of the one-inch R29 ring radiator, resulting in low resonance frequency, but further provides the extended dispersion characteristics of a ¾-inch dome. Tymphany’s unique AirCirc Magnet System -- named for the way it optimizes air flow within the chamber – rearranges the traditional magnet structure from a single magnet to an open magnetic circuit comprised of six separate neodymium slugs. This, in combination with the chamber, results in the elimination of the reflections and resonances that compromise the performance of traditional motors. The D3004/6600 gives engineers improved control over critical midrange performance, for superb vocal rendition and excellent imaging at all listening locations.
