Quick look at Ex Machina Poseidon:The Ex Machina Poseidon is a compact, passive subwoofer pair designed as the dedicated low-frequency extension for Selene monitoring systems. Powered directly by Selene’s EXCore amplifier and DSP, Poseidon requires no external amplification or bass management, integrating automatically as part of a calibrated system. A high-excursion 16cm Epique MMAG driver delivers deep, controlled low end from a small footprint, transforming Selene into a true 3-way monitor. With zero-phase LR4 crossover integration and system-level calibration handled by EXCore, Poseidon delivers accurate, phase-coherent bass that behaves like a natural extension of the main monitors—ideal for immersive, stereo, and low-frequency-critical work. Ex Machina Poseidon Features:
- Compact passive subwoofer pair designed exclusively for Selene
- Powered directly from Selene’s EXCore amplifier and DSP
- High-excursion 16cm Epique MMAG driver with 14.7mm Xmax (each way)
- Zero-phase LR4 crossover integration at 150Hz
- Transforms Selene into a complete 3-way monitoring system
- Compact footprint with surprising low-frequency output
- Designed for accurate integration, not standalone use
The Ex Machina Poseidon is the dedicated low-frequency extension for Selene monitoring systems. Designed as a passive subwoofer pair powered directly by Selene’s EXCore amplifier and DSP, Poseidon integrates seamlessly without external amplification or bass management. A high-excursion 16cm Epique MMAG driver delivers deep, controlled bass from a compact enclosure, extending Selene into a true 3-way system. Zero-phase LR4 crossover integration preserves phase coherence and transient accuracy, ensuring reliable translation for immersive, stereo, and low-frequency-critical work.
WHY IT’S DIFFERENT
Most compact subs rely on aggressive voicing or room compensation to sound bigger than they are. Poseidon takes a different approach—high linear excursion, controlled integration, and system-level calibration through EXCore. The result is accurate, controlled low end that behaves like part of the main monitor, not a separate bass source.
As such, Poseidon is perfect for the following applications:
- Immersive and ATMOS monitoring systems
-
Compact 3-way stereo monitoring
-
Low-frequency-critical mixing and sound design
-
Space-constrained control rooms and edit suites
SYSTEM INTEGRATION AND CALIBRATION
Poseidon contains no internal amplification or DSP. All power, crossover integration, time alignment, and calibration are handled by Selene’s EXCore unit. When connected, EXCore applies the appropriate crossover and system calibration automatically, ensuring Poseidon integrates as a seamless extension of the Selene monitors. Over-the-air firmware and calibration updates applied to EXCore extend to the complete Selene + Poseidon system.
