The story
Gravis VI uses two 12.6-inch long-throw woofers with honeycomb sandwich cones in a sealed cabinet, driven by a 1,700 W RMS (2,400 W peak) Class AB amplifier. Like Gravis III and V, it is set up through the Sonus faber app: four presets, a 40 to 150 Hz crossover, continuously variable phase, delay, up to eight parametric EQ filters and automatic room calibration.
Sonus faber pairs Gravis VI with the Reference collection. It reaches 18 Hz (−6 dB), so it adds the bottom octave and the scale that large rooms and full-range systems need. Balanced and Speakon inputs let it connect directly to a high-end preamp or stereo amplifier.
Also offered with a 45-degree grain top and inlaid Sonus faber logo in Red, Wenge, Graphite or Piano Black (the "Ref&Trad" options on this page).
