Sonus faber Gravis III Powered subwoofer (Each)

Overview

The Sonus faber Gravis III is a powered subwoofer using a 250 mm long-throw woofer and a 600-watt RMS Class AB amplifier. It brings its own amplification to the bass section of a stereo or home theater system.

Why This Model Matters

Its sealed enclosure and app-controlled processing provide a more adjustable integration platform. The app includes presets, crossover and phase controls, parametric equalization, delay, and automatic room calibration. It is also compatible with the separately sold Gravis Transmitter. Placement and adjustment are as important as output capacity: the subwoofer should work with the main speakers and the room rather than simply add more bass level. The built-in amplifier accepts an appropriate signal from the system, so a separate speaker-level power amplifier is not needed for the subwoofer itself.
