Opera Diamond

The Opera Diamond is similar to the Opera, but is equipped with a 30mm diamond tweeter from Accuton.

In addition, the crossover was adapted to the diamond tweeter using the best available components from Duelund.

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 crossover and to all chassis consists of solid pure silver conductors with GORE dielectric made of extruded Teflon.


For the highest demands, the tweeter has a 30 mm diamond dome, the capacitor in front of 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.
