AMPHION ONE18

Amphion One18X: the studio all-rounder, refined further

One18X is the next evolutionary stage of the revered One18, Amphion's trusted "modern workhorse" model, praised for over a decade by audio engineers worldwide (Adele, Kendrick Lamar, SZA, Rihanna...). A state-of-the-art tweeter and newly engineered crossover enhance its clarity, resolution, and transient precision. Now benefiting from a highly linear, ultra-low distortion tweeter, the One18X not only preserves its previous iconic status as a well-translating modern nearfield, it raises the benchmark of a trusted studio monitor even further.

The listening experience

Thanks to phase coherence and pinpoint imaging, the One18X translates precisely to any playback device, correctly reproducing spatial information in width, height and depth. Amphion's advanced acoustic design minimizes electrical clutter, preserving signal purity that lets you harness the full power of modern DSP, room correction and other advanced software. The sound stays clear and memorable even at lower listening volumes, with even dispersion that isn't limited to a single sweet spot.
