The Ex Machina Poseidon is a compact passive subwoofer pair designed exclusively for Selene, featuring a 16 cm Epique MMAG driver with 14.7 mm Xmax, a 150 Hz zero‑phase LR4 crossover, direct power from Selene’s EXCore amplifier, and a maximum SPL of 98 dB at 50 Hz.

Key Features

Poseidon delivers deep, controlled bass from a surprisingly small enclosure while preserving phase coherence across the entire system. Its high‑excursion driver provides linear movement for accurate low‑frequency reproduction, and the zero‑phase LR4 crossover integrates seamlessly at 150 Hz, eliminating timing errors. By drawing power directly from Selene’s EXCore unit, the subwoofer avoids external amplification or additional DSP, simplifying setup and reducing clutter. The design targets immersive, ATMOS‑enabled monitoring environments and space‑constrained control rooms where precise low‑end extension is essential.

System Integration & Calibration

All power, crossover processing, time‑alignment, and calibration occur within Selene’s EXCore, meaning Poseidon behaves as a natural extension of the main monitors rather than a separate bass source. Firmware and calibration updates delivered over‑the‑air to the EXCore automatically propagate to the complete Selene + Poseidon system, ensuring consistent performance without manual intervention.

Specifications

The unit houses a 16 cm Epique MMAG driver capable of 14.7 mm linear excursion each way, paired with a 150 Hz zero‑phase LR4 crossover. It achieves a peak SPL of 98 dB at 50 Hz and operates solely as a passive component powered by Selene’s EXCore amplifier. Compatibility is limited to Selene systems, and the product carries a six‑year warranty.

Warranty, Support & Updates

Poseidon includes a six‑year warranty covering manufacturing defects. System‑level calibration is managed through Selene’s EXCore, and over‑the‑air firmware updates keep the subwoofer aligned with the latest performance standards.
