Tweeter à dôme Visaton KE 25 SC 8 OHM
[KE 25 SC-8] Avis/Critiques 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. A completely new feature is the integrated impedance linearising function using an 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.
