Still the absolute finest music system available today. In its Series VII version, the WAMM possessed unrivaled harmonic rightness, startling dynamic contrasts, with the ability to flow with the music like none other - this was the world's ultimate personalized reference speaker system.

It included a high performance equalizer and low frequency electronic crossover. Custom calibration was done by David Wilson in person, in your listening room.
