Unparalleled Precision for Maximum Mixing Confidence
Engineers demanding uncompromising accuracy and flawless translation will find all that and more in the Ex Machina Soundworks Terra. This powered 3-way coaxial studio monitor offers picture-book precision, boasting an astonishing 40Hz to 30kHz frequency response, immaculate phase coherence, robust SPL capability, and a wide, remarkably coherent sweet spot. The Terra melds individually measured and DSP-linearized custom coaxial midrange/tweeter drivers and modified PuriFi low-frequency drivers, with zero-phase crossovers for letter-perfect time alignment and imaging. Moreover, this premium-caliber speaker is housed in an ultra‑rigid monocoque aluminum cabinet with advanced damping, Durasein side panels, and targeted metamaterial absorbers to eliminate resonance and internal modes. You also get transparent electronics built around a SHARC‑based DSP platform, AKM converters, and Hypex NcoreX amplification, ensuring that the harmonic distortion of the electronics chain remains well below the acoustic distortion of the drivers themselves. Finally, each Terra is individually calibrated and leverages over-the-air calibration updates to ensure continuous optimal performance, and you get optional Gravity subwoofer integration for extended low-frequency performance in larger spaces.

Purpose-built drivers, engineered for accuracy
The Terra employs two purpose-built driver types, each optimized for its specific task and integrated for maximum coherence and accuracy. The third-generation, 7-inch coaxial midrange/tweeter flaunts custom TPCD diaphragms with improved fiber layup, an FEA-optimized hybrid motor structure that minimizes distortion, and automated fiber placement that pushes tweeter breakup above 40kHz and utilizes DSP to limit high-frequency extension to 30kHz. A thin‑lip underhung surround eliminates phase cancellation, while carefully engineered waveguide geometry maintains a true point‑source acoustic center for precise imaging. Low frequencies are handled by a custom-modified, 7-inch PuriFi woofer, fitted with a concave aluminum diaphragm to maximize bending stiffness. Moreover, PuriFi’s hybrid motor structure and symmetrical surround geometry certify fast settling time, exceptional linear excursion, and dramatically reduced distortion and compression. Lastly, both drivers are individually measured and linearized before crossover application, ensuring that the acoustic output matches the DSP model exactly and performs as intended.
Reference-grade signal integrity
Engineered for the utmost in transparency, the Ex Machina Soundworks Terra’s electronics and DSP ensure that nothing is added or obscured between the input signal and the sound that reaches your ears. This state-of-the-art studio monitor benefits from third-generation Peregrine DSP architecture, built around an Analog Devices SHARC+ processor and an ESP32 coprocessor that provides Wi-Fi control and connectivity. Both A/D and D/A are handled by AKM’s flagship converters, selected for measured performance rather than marketing specifications. Hypex NcoreX modules — NCx252MP for the woofer and midrange and NCx‑102EXT for the tweeter — deliver world-class amplification with exceptional efficiency and vanishingly low distortion. Taken together, the total harmonic distortion of the Terra’s entire signal path sits well below the acoustic distortion limits of the drivers themselves, rendering the electronics sonically invisible.
Monitoring that never stops getting better
Driven by the third generation of Ex Machina Soundworks’ proprietary IRC and DSP architecture, the Terra allows for precise, independent control of each driver with discrete, perfectly phase‑summed corrections applied at the transducer level. Because each driver is measured individually and crossovers are zero-phase, the Terra achieves flawless phase tracking at crossovers without interpolation from sine-sweep measurements, resulting in real-world phase accuracy rather than a measurement that merely looks good on paper. Beyond that, each Terra is individually measured and calibrated, with each driver linearized separately and zero‑phase crossovers applied at 200Hz and 2kHz to achieve a ±1.5dB frequency response and ±15-degree phase deviation across the full 30Hz to 30kHz operating range. Additionally, the studio experts at Sweetwater have found that since all units are calibrated to the same reference target, you can deploy any two Terras as a matched pair with absolute confidence. An onboard ESP32 coprocessor rounds out the Terra’s cutting-edge DSP, providing you with periodic over-the-air DSP updates, allowing it to continuously improve its calibration accuracy as measurement data, models, and algorithms evolve.
