Illuminator 1" Tweeter
ScanSpeak
Type Number:D3004/660000

Features

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 and back chambers are die cast in aluminum for a beautiful look with maximum mechanical stability. The back chamber is designed with a contoured shape that functions as a heat sink in high power applications. The magnet is positioned away from the heat source for minimal thermal compression. The Illuminator tweeters are optimized to offer small package sizes that can fit into tight spaces such as compact cabinets and automotive trim pieces.

Driver Highlights: 1" soft dome, AirCirc Magnet System, aluminum faceplate
