Ex Machina Soundworks SELENE + POSEIDON – Complete Compact 3-Way Monitoring System
OVERVIEW
SELENE + POSEIDON is Ex Machina Soundworks’ compact full-range monitoring system, designed for immersive, multi-channel, and space-constrained studios. SELENE coaxial monitors pair with dedicated POSEIDON subwoofers powered directly by the EXCore amplifier and DSP, forming a unified 3-way system without external amplification or bass-management complexity. Zero-phase LR4 integration preserves phase coherence and transient accuracy, extending system response to 50Hz linear (F6 at 35Hz) while maintaining consistent imaging across all channels. The result is full-range performance from a compact system that scales effortlessly from stereo to immersive workflows.
KEY HIGHLIGHTS
Who is it for?
Immersive and ATMOS studios requiring compact, consistent monitoring across multiple channels. Engineers working in space-constrained rooms who need full-range accuracy without large enclosures. Producers seeking a complete professional monitoring system that scales easily from stereo to multi-channel setups.
Why is it Different?
Most compact systems rely on compromised satellites and generic subs. SELENE + POSEIDON is engineered as a unified system, using the same coaxial design philosophy, phase coherence, and calibration approach across every component. Shared amplification and DSP through EXCore ensure the entire system behaves predictably, delivering accurate translation without integration headaches.

SYSTEM INTEGRATION & CALIBRATION
SELENE + POSEIDON operates as a unified 3-way monitoring system powered entirely by the EXCore amplifier and DSP. All amplification, crossover integration, time alignment, and calibration are handled at the system level, ensuring consistent frequency response and phase behaviour across all channels. Each system is individually calibrated, and over-the-air firmware and calibration updates allow long-term performance improvements as Ex Machina’s measurement models evolve.
