One25A: Three-way Active Studio Monitor
Amphion One25A is a 3-way studio monitor that is true to Amphion core strengths of advanced acoustic design, simple signal path, naturalness and high level resolution enhanced with the benefits of active design, without any of the downsides.
Know-how from the highest level of instrument building was applied for resonance control
and energy transfer to ensure that not only the technical, but also goals regarding emotionality and musicality, were met. An innovative sealed dual cabinet improves clarity of all frequencies by separating the midrange from the hexagon shaped bass enclosure, which eliminates standing waves. Plenty of amplifier headroom, elegant simple active crossover, and protection limiter, which is only in the signal path when needed all contribute to highest level of resolution.
Compact design, classic Amphion performance
To achieve the highest signal integrity and the sonic transparency Amphion is known for, a minimalistic cross-over design was needed. Building on the 2-way active circuitry of the Amphion Base-units, a mastering grade resolution is now available in an active 3-way monitor. Key factors such as high bandwidth, no higher order or cross-over distortion and excellent signal-to-noise ratio translate into an effortless and rich listening experience.
In terms of electronics, One25A’s matched amplifiers provide excellent headroom and full-range power suitable for all applications including music creation, film and TV scoring, and audio post-production. Electronic components are located on the exterior and are well isolated from the speaker enclosure, which not only improves performance but ensures long life and easy serviceability as well as adaptation to soffit mounting. As with Amphion’s passive monitor designs, the One25A achieves the benefits of pure, short, signal path that maximizes dynamics, resolution, and emotional transfer.
Electronic components are located on the exterior and are well isolated from the speaker enclosure, which not only improves performance but ensures easy serviceability as well as adaptation to soffit mounting.
