About LOG Audio

LOG Audio is an Austrian manufacturer of fully active high-end loudspeaker systems based in Graz. At the heart of the products is the LOG AudioEngine: it transfers the audio signal consistently in digital form, avoids unnecessary D/A conversions, calculates digital crossovers and corrects the sonic characteristic of each speaker driver. Each driver is powered by its own Class-A/B power amplifier, so that amplifiers, converters and electronics are fully integrated in the loudspeaker – without external components and without cable clutter. The product range includes the 3-way floorstanding loudspeakers CUBE, ESPRIT and VIVANT as well as the digital phono preamplifier PROLOG for playing vinyl LPs. Planning, development and production take place exclusively in Austria; the materials used for assembly are sourced from qualified partner companies in the EU. Every system undergoes an elaborate tuning process involving measuring instruments and the human ear. The systems are sold, among other channels, through demonstrations at home or on site.
