The 25 mm / 1" high-end tweeter BRAX GRAPHIC GL1 is the first of its kind that comes with an innovative ceramic aluminium dome. Its sophisticated material requires a complex manufacturing process in which a plasma flame melts a ceramic powder on the surface of an aluminium substrate. The result is a tweeter dome that combines outstanding stability with low moving mass and high inner damping - perfectly made for brilliant and compression-free treble reproduction. The integrated, with Merino wool damped coupling volume reduces the resonance frequency and therefore allows lower crossover frequencies.
