Ex Machina Gravity Pair

The Ex Machina Gravity is a 26 cm passive sub‑woofer pair that integrates directly with the Terra monitor system, delivering linear response down to 30 Hz, 112 dB SPL at 1 kHz and a unified 2.2 architecture that preserves stereo bass accuracy without external amplifiers or bass‑management hardware.

Overview

Gravity expands the Terra platform by adding a side‑firing, shallow‑enclosure sub‑woofer that draws power from Terra’s rear‑panel amplification. The unit employs a zero‑phase LR4 digital crossover set at 80 Hz, which the Terra DSP applies automatically, eliminating the need for manual level‑matching or phase‑alignment adjustments. With user‑adjustable delay compensation and gain trim, engineers can fine‑tune the system for any control‑room size while maintaining tight timing and coherent low‑frequency translation.

Technical Highlights

The sub‑woofer houses a single 26 cm PuriFi driver in each cabinet, mounted in a compact 305 × 215 × 305 mm chassis that fits on‑wall or near‑field positions. Its VESA‑compatible mounting (200 × 200 mm, M6) simplifies installation, and the total weight of 20.4 kg per unit ensures stability without excessive bulk. By leveraging Terra’s built‑in amplification, Gravity achieves a maximum system SPL of 112 dB at 1 m (106 dB at 50 Hz) while keeping the overall system response within ±1.5 dB from 30 Hz to 30 kHz.

Integration & Calibration

When connected, Terra recognises Gravity instantly and applies the appropriate crossover and calibration data over‑the‑air. This seamless integration removes the typical workflow of configuring external sub‑woofers, allowing users to focus on creative decisions rather than technical setup. Firmware and calibration updates delivered to Terra propagate automatically to the combined system, ensuring ongoing performance improvements without additional effort.
