Ex Machina Poseidon Compact Passive Subwoofer (Pair)

The Ex Machina Poseidon is a high-performance compact passive subwoofer system designed to extend low-frequency accuracy and impact in professional monitoring environments. Developed by Ex Machina, Poseidon delivers fast, controlled bass reproduction while maintaining phase coherence and clarity for critical listening applications.

Engineered to integrate seamlessly with Ex Machina’s compact reference monitors, Poseidon provides authoritative low-end extension without sacrificing speed or definition. Its passive design allows engineers to choose external amplification and system processing that best suits their studio workflow, offering maximum flexibility in high-end installations.

The compact enclosure is constructed to be acoustically inert, minimizing resonance and coloration so low-frequency information remains tight, accurate, and translatable. When used as a stereo pair, Poseidon preserves balance and symmetry across the listening field, making it well suited for nearfield monitoring, immersive audio, and space-constrained control rooms.
