Ex Machina Selene + Poseidon Combo

The Ex Machina Selene + Poseidon Combo is a compact, full-range 3-way monitoring system designed for immersive, multi-channel, and space-constrained studios where accuracy and phase coherence matter most. By pairing Selene coaxial monitors with dedicated Poseidon subwoofers powered directly by the EXCore amplifier and DSP, this system delivers consistent imaging, controlled low-frequency extension, and scalable performance without external amplification or bass management complexity.

Zero-phase LR4 crossover integration preserves transient accuracy and phase alignment across the entire system, extending low-frequency response to 50Hz linear (F6 at 35Hz) while maintaining uniform behavior across stereo and immersive formats. Built with the same aerospace-grade construction and measurement-driven design philosophy found throughout the Ex Machina lineup, Selene + Poseidon provides full-range performance from a compact footprint that scales effortlessly from stereo monitoring to ATMOS and multi-channel workflows.

Key Features

System Integration & Performance

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 behavior across every channel. Each system is individually calibrated, and over-the-air firmware and calibration updates allow performance to evolve as Ex Machina’s measurement models advance.
