„Was man hier an Fein-wie Grobdynamik hören kann, welche Präzision und Detailfülle, das ist fraglos State Of The Art.“

The components of the crossover consist of extremely high-quality mica capacitors and film capacitors from Duelund, Intertechnik, Mundorf and BMC.

The entire internal wiring from the pole terminals to the switch as well as to all chassis consists of solid pure silver conductors with GORE dielectric made of extruded Teflon.

For the highest demands, the tweeter has a 30mm diamond dome, the capacitor in the crossover for the tweeter is made of solid pure silver foil with pure silver connections, the cables in the tweeter range consist of a pure silver solid conductor.
