The Opera is currently the largest floorstanding speaker in purist ETA design with larger bass drivers and larger midrange drivers from Accuton’s cell line. This full-range speaker is suitable for medium to large rooms. Its independent design with the clear design language in the Bauhaus style blends harmoniously into a timeless living environment without imposing itself visually.

The best available material selection from the chassis used to the pure silver inner wiring to the exclusive switching components and the ultimate housing materials is the basis for the outstanding sound characteristics of the Opera.

Silver Edition

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.

Diamant Edition

For the highest demands, the tweeter has a 30mm 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 silver-gold solid conductor.

Opera Grandezza 

In addition to the 30 mm diamond tweeter, the midrange diaphragm is also made of pure diamond. It is the world’s largest diamond midrange driver with its 90 mm diaphragm made of pure industrial diamond, also from Accuton. AudiaZ is currently the only German manufacturer to use this state-of-the-art loudspeaker.
