Spherical horns calculated with own software are bundled with specific tweeter and midrange drivers - both soft dome silk drivers. To add similar quality in the bass department preserving the still compact size the 10quot; woofer is powered and controlled by own 500W amplifier - to meet the high sensitivity of mid/highs. The form factor of the robust housing and specific damping sure helps a lot. As we listened over 6 hours I could watch how quick the sound warmed up and the reproduced music showed its tension, emotion and power. Tonality was smooth. So an interesting newcomer in the upper price class and extravagant design plus perfect building quality.br/ a href="http://www.viennaphysix.at"; target="_blank"strongVienna Physix/strong/a
