Magnetically shielded 25 mm (1") high end dome tweeter made of ceramic for crystal clear, perfectly reproduced sound  even at high volume settings and with no distortion. The pole piece  perforation coupled with the flow-optimised rounded shape, the damping in the cavity and the ventilated voice coil carrier guarantee a very low resonance frequency. The impedance  is linearised by means of an integrated LRC element. This means that  the dome can be easily integrated in a network of crossovers. The  protective grille is fitted on the inside with an acoustic low-pass filter  in the shape of a transparent ring, which does not begin to operate  until 25 kHz are achieved, when it damps any material-borne resonance.  The grille has the added advantage of improving omnidirectional sound distribution at higher frequencies.
