Ex Machina Soundworks GRAVITY – Passive 26cm/10″ Subwoofer (Pair)

OVERVIEW

GRAVITY is the low-frequency extension designed specifically for TERRA. A passive 26cm/10″ 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 80Hz, GRAVITY extends TERRA’s response to 30Hz linear (F6 at 20Hz) while increasing system headroom to 112dB @ 1kHz.

The compact, side-firing design enables nearfield placement alongside TERRA, preserving stereo bass accuracy and minimising room-mode excitation. TERRA is complete on its own; GRAVITY is for when deeper extension or higher SPL is required.

KEY HIGHLIGHTS

Who is it for?

TERRA users working in film, game audio, immersive formats, or larger rooms who require deeper low-frequency extension and higher SPL without compromising phase coherence or translation.

Why is it 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.

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

Quick Points

• Designed exclusively for TERRA – no third-party sub integration.
• Passive design powered from TERRA’s back panel – no external gear.
• Zero-phase crossover means no bass smear or timing issues.”
• 2.2 configuration keeps stereo bass information accurate.
• TERRA is complete. GRAVITY is for when you need deeper extension.
• Side-firing, shallow cabinets – easy to place, even on-wall.

SYSTEM INTEGRATION & 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.
