Ex Machina Selene Pair

The Ex Machina Soundworks Selene is a compact coaxial reference monitor system that delivers ±1.5 dB accuracy from 80 Hz to 30 kHz, offers a maximum SPL of 106 dB at 1 m, and integrates an external EXCore amplifier and DSP unit for immersive‑and‑ATMOS workflows.

Key specifications

The Selene pair houses a 16 cm coaxial driver driven by the EXCore rack, which supplies amplification, crossover processing and real‑time calibration. The passive 3 kHz LR2 crossover preserves phase coherence, while the HF DSP limits output to 30 kHz for optimal performance. Connectivity routes through the EXCore unit, and mounting follows the MIS‑D VESA 100 × 100 or 75 × 75 standard. The unit carries a six‑year warranty and receives over‑the‑air firmware and calibration updates via Wi‑Fi.

Design and construction

Ex Machina engineers the enclosure to aerospace‑grade tolerances, ensuring rigidity and thermal stability. The true coaxial layout aligns the tweeter behind the woofer, producing consistent imaging across wide listening angles. Each speaker pair operates as a self‑contained system, eliminating the need for shared amplification or DSP and simplifying scalable multi‑channel installations.

Calibration and integration

The external EXCore unit measures each Selene system individually, then applies linearised DSP that corrects the loudspeaker itself rather than the room. This pure‑monitoring approach guarantees honest playback and reliable translation from mix to final product. Firmware and calibration data push automatically, keeping the system aligned with the latest Ex Machina measurement models.

Applications

Professionals use Selene for immersive and ATMOS monitoring, height‑channel and surround setups, compact near‑field stereo work, mobile mixing rigs and multi‑room studio expansions. Its small footprint fits bedroom studios while still meeting the rigour of commercial facilities.
