Dome Tweeter (400-1276B) Features Faxback Doc. # 14217 This REALISTIC Dome Tweeter has been specifically designed for high power, high frequency response with a cross-over at 4000 Hz (or above). The diaphragm is dome-shaped which results in good dispersion (avoiding "point source" sound so often associated with tweeters) and produces a superior polar pattern. Because of the low cone mass, transient distortion is held to a minimum. (ALL-03/16/95)
