New ICHOS Schallwandler Vienna One Speakers

ICHOS Schallwandler writes: “After more than 2.5 years of development and countless listening tests as well as the construction of various prototypes, we are proud to present our reference loudspeaker.”  

With the challenges of today’s architecture as well as the question of size, we have dealt extensively and implemented in the new series – VIENNA. The result is a loudspeaker system equipped with active basses which are in use up to approx. 80 Hz. Of course, we use hard-suspended basses, so the dynamics is preserved in full. The available amplifier module includes a complete dsp and allows an exact adjustment to your listening room.


  • Tweeter unit: AMT with waveguide, modified as a dipole in an aluminum cabinet decoupled from the main cabinet. Crossover components from Duelund. Internal wiring pure copper with pure silver coating and Teflon sleeve.
  • Low/midrange: 25 cm paper ribbon, fully treated.
  • Efficiency passive: 95 dB/1W
  • Low frequency range: 2 x 25 cm bass drivers in carbon sandwich construction, separate closed enclosures. Thus, they work in the bass particularly precise and are not critical in the placement. Thanks to the electronic bass equalization, the subwoofers could be built relatively compact. The built-in amplifier (plate-amp) is equipped with 2 power amplifiers in bridge circuit and a power of 350 watts RMS, frequency range 20 Hz(-3dB) – 100 Hz adjustable
  • Crossover with DSP, individual setup on site is possible.
  • The most important parameters can be set on the rear panel: Volume (input level adjustment) Bass Roll-Off, Bass Low Filter, Bass at 60 Hz additionally adjustable.
  • Three high-quality, separate power supplies for power amplifiers, control and signal processing
  • Triple filtered power supply for the power amplifiers
  • Microcontroller control for:
  • Overload protection by means of special protection circuit
  • Overtemperature protection
  • automatic switch-on or remote switch-on
