The System

Not two products. One system.

Terra reaches 40Hz linear and stops. Not because the engineering ran out, but because a near-field monitor has physical limits. Gravity picks up exactly where Terra leaves off, extending the system to 30Hz linear without introducing a single additional control point, crossover adjustment, or phase alignment decision.

The result is a fully realized, full-range loudspeaker system for professionals who demand accuracy at every frequency. Not a monitor with a subwoofer bolted on. A system that was designed as one from the beginning.

Gravity is passive. Power, DSP, crossover, and calibration all come from Terra's rear panel. One system, one control point, one calibration update path. No level matching, no separate bass management processor, no phase guesswork.

System Integration

One rear panel. One system.

Gravity draws power and signal from Terra's rear panel. There is no external amplifier to match, no bass management crossover to configure, no time alignment to guess at. Terra's DSP controls the entire system, the crossover, the calibration, the over-the-air updates. Add Gravity and the system extends. Nothing else changes.

This is not a convenience feature. It is the reason the two behave as one. There is no seam at the crossover because there is no independent system on either side of it.

Performance

30Hz linear. 112dB. ±1.5dB end to end.

The integrated system delivers ±1.5dB frequency response from 30Hz to 30kHz, F6 at 20Hz, and 112dB continuous SPL at 1kHz. Phase coherence is maintained across the full range because the crossover is handled by Terra's DSP, not a separate analog network.

For film, game audio, immersive formats, and rooms where the low end is part of the work, this is the system. For everything else, Terra is already enough.
