Quick look at Ex Machina Gravity:The Ex Machina Gravity is the dedicated low-frequency extension for Terra, designed to function as a true part of the system rather than a traditional add-on subwoofer. This passive 26 cm subwoofer pair is powered directly from Terra’s rear-panel amplification and integrated through coordinated DSP, eliminating the need for external amps, bass management, or phase alignment. Using a zero-phase LR4 crossover at 80 Hz, Gravity extends Terra’s response down to 30 Hz linear (F6 at 20 Hz) while increasing system headroom to 112 dB @ 1 kHz. Its compact, side-firing design supports accurate stereo bass and nearfield placement while minimizing room-mode interaction. Terra operates as a complete system on its own, but Gravity delivers deeper extension, higher SPL, and seamless integration for film, immersive, and low-frequency-critical monitoring environments. Ex Machina Gravity Features:
- Passive 26cm subwoofer pair designed exclusively for Terra
- Powered directly from Terra’s rear panel amplification
- Extends system response to 30 Hz linear (F6 at 20 Hz)
- Zero-phase LR4 crossover at 80 Hz for seamless integration
- Compact 2.2 architecture preserves stereo bass accuracy
- Side-firing design minimizes room-mode excitation
- Shallow enclosure suitable for nearfield or on-wall placement
- User-adjustable delay compensation and gain trim
The Ex Machina Gravity is the low-frequency extension designed specifically for Terra. A passive 26cm subwoofer pair powered directly from Terra’s rear panel amplification, Gravity integrates as a single, unified system—no external amplifiers, no bass management processors, no phase-alignment guesswork. Using a zero-phase LR4 crossover at 80 Hz, Gravity extends Terra’s response to 30 Hz linear (F6 at 20 Hz) while increasing system headroom to 112 dB @1 kHz. The compact, side-firing design enables nearfield placement alongside Terra, preserving stereo bass accuracy and minimizing room-mode excitation. Terra is complete on its own; Gravity is for when deeper extension or higher SPL is required.
WHY IT’S DIFFERENT
Adding subs usually means phase alignment headaches, mismatched amplification, and unreliable bass management. Gravity eliminates those problems by design. Powered directly from Terra and integrated through coordinated DSP, Gravity behaves as an extension of the main system—not an add-on fighting for control. As such, Gravity is perfect for the following applications:
- Film and game audio monitoring
-
Immersive and low-frequency–critical content
-
Larger control rooms requiring extended headroom
-
Stereo monitoring where bass accuracy and translation matter
SYSTEM INTEGRATION AND CALIBRATION
Gravity contains no internal amplification or DSP. All power, crossover integration, time alignment, and calibration are handled by Terra’s rear panel electronics and DSP. This integrated approach eliminates level-matching, phase-alignment, and bass-management challenges common to traditional subwoofer setups. When connected, Terra automatically applies the appropriate crossover and system calibration, ensuring Gravity operates as a seamless extension of the main monitors. Over-the-air firmware and calibration updates applied to Terra extend to the complete Terra + Gravity system.
