Scanspeak R2604/833000 Discovery Range. Replaces Vifa XT25BG-60-04.
This 26 mm dual ring radiator with centre phase plug has a low distortion response curve that extends effortlessly to above 40kHz. A double magnet system with tuned rear chamber yields an exceptionally low resonant frequency of just 440 Hz, which is a long way below the recommended crossover frequency - this tweeter is easy to use.
