The Complete Range

Every application. One standard.

Scoring a film. Mixing an album. Tracking a vocal at 2am. Uncompromising accuracy, every time.

Monitors
Coaxial monitor
Ex Machina Selene Pair
Selene Pair
Turns out six inches IS enough...

Professional monitoring doesn't require large cabinets. It requires cabinets engineered to disappear acoustically, regardless of physical dimensions. Immersive channels, surround positions, nearfield stereo pairs.

±1.5dB   80Hz–30kHz Freq. Response
±15°   30Hz–30kHz Phase Coherence
106dB @ 1kHz Max SPL
Selene bass extension system
Ex Machina Poseidon Pair
Poseidon Pair
...but sometimes you need it to go deeper.

Selene handles everything immersive demands. When you need full-range stereo decision-making, Poseidon integrates via EXCore and extends response to 35Hz, no extra amplifiers, no additional processing.

50Hz linear (F6 at 35Hz) System Freq.

Selene + Poseidon Combo
Hey...Nice Stack!

Selene is complete for immersive applications. When the project demands full-range decision-making, Poseidon closes the gap. Together they reach 50Hz linear, F6 at 35Hz, in a footprint that fits on any desk. One system. No compromises.

Near-field monitor
Ex Machina Terra (Nocturne)
Terra
Work with conviction, not hope.

Terra is engineered like a precision instrument, not furniture. Every component is designed to be acoustically invisible, the cabinet doesn't resonate, the drivers don't color, the electronics don't add noise. What you hear is your work, nothing else.

±1.5dB   40Hz–30kHz Freq. Response
±15°   30Hz–30kHz Phase Coherence

Ex Machina Terra (Bone)
Terra (Bone)

Same high precision engineered studio monitor as Terra, with Bone white side panels.

Ex Machina Gravity Pair
Gravity Pair
Mass creates gravity...So does Terra

Terra is complete for most work. When the project demands film, game audio, immersive formats, or a larger room, Gravity extends the system to 30Hz linear, powered directly from Terra's rear panel.

Feel the weight of every decision.

Terra is complete for most work. When the project demands more, Gravity completes the system. Together they reach 30Hz linear, 112dB continuous, with the same phase coherence and translation accuracy that makes Terra the reference. One system. Zero compromises.

Arcturus
The search ends here.

When the room is the instrument and the session is the record, you need monitors that never lie. Arcturus is what we built for those rooms. Twin SEAS Extreme Series subwoofers. TeXtreme coaxial mid/tweeter.

Complete Systems

Every system is designed as a system.

Every system is verified against the same target. No afterthought integrations, no compromise crossovers. The whole is more accurate than the sum of its parts.
