The Illuminator tweeters continue on with the heritage of the renowned Revelator D29. The large-roll surround and textile dome diaphragm provide a flat frequency response to above 30KHz with outstanding off-axis dispersion.
The face plates are die cast in aluminum for a beautiful look with maximum mechanical stability.
Scan-Speak’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 gives engineers improved control over critical midrange performance, for superb vocal rendition and excellent imaging at all listening locations.
The back chamber is die cast in aluminium and designed with a contoured shape that functions as a heat sink in high power applications.
