Ex Machina Poseidon

Ex Machina Poseidon is a premium passive studio monitor subwoofer (sold as a matched pair) engineered strictly as a dedicated low-frequency extension for the Ex Machina Selene monitoring system. Rather than serving as a generic add-on, it functions as an acoustic component fully integrated into the EXCore DSP architecture. This specific configuration offloads sub-bass duties from the main coaxial drivers without sacrificing phase coherence, effectively transforming the two-way Selene into a true, compact three-way system built for critical stereo mixing and complex Dolby Atmos configurations.

Phase-Coherent Bass Without the Guesswork

Pairing nearfield monitors with third-party subwoofers regularly introduces transient smearing, group delay, and time-alignment issues at the crossover region. The Poseidon circumvents classic bass-management headaches by utilizing a zero-phase LR4 crossover at 150Hz, calculated natively by the Selene’s external EXCore amplifier/DSP module. This proprietary routing grants audio engineers a surgically tight low-end response, hyper-accurate stereo bass imaging, and a massive increase in overall system headroom.

Extreme Excursion in a Micro Footprint

Built around a custom 6.3-inch Epique MMAG driver boasting an immense 14.7mm of linear excursion in each direction, the Poseidon delivers articulate, deep bass output reaching up to 98dB of continuous SPL at 50Hz. Crucially, this extension is generated from an ultra-rigid, acoustically inert 6.5-inch extruded aluminum cube. Such a compact footprint allows for seamless physical deployment into space-constrained control rooms, editing suites, and dense multi-channel immersive arrays without obstructing sightlines or creating comb-filtering reflections off consoles.
