Amphion One25A is a three-way active studio monitor that represents the culmination of Amphion’s 25-year commitment to advanced acoustic design, refined signal paths, and meticulous craftsmanship, enhanced through active operation without the typical compromises associated with active loudspeakers.
Amphion One25A is engineered to deliver industry-leading translation, allowing engineers to trust monitoring decisions and maintain focus, speed, and consistency across demanding professional workflows. Strong phase coherence and pinpoint imaging enable accurate judgement of width, height, and depth, ensuring mixes translate reliably to all playback systems.
Unlike many active designs, Amphion One25A avoids DSP and AD/DA stages, preserving maximum resolution through a simple, carefully controlled signal path. The midrange and tweeter operate within an isolated sealed chamber, minimising interference from bass driver pressure and ensuring high midrange and treble clarity.
A sealed dual-cabinet construction with extensive internal bracing acts both as a stiffening structure and an energy dispersion filter, using controlled mass and coupling to manage enclosure resonance. Acoustic symmetry around the midrange supports smooth response and precise imaging, aided by Amphion’s fifth-generation U D D technology for improved driver integration and in-room performance.
Designed for flexibility in professional control rooms, Amphion One25A is well suited to soffit mounting, with a removable external amplifier pack housed in a rigid steel enclosure to minimise mechanical interference and support alternative installation options. Boundary control allows precise low-frequency adjustment to suit room placement, while an intelligent protection circuit operates only when required, maintaining uninterrupted workflow without muting or signal interruption.
