A reference monitor remaining true to Amphion’s core strengths with the benefits of an active design

The One 25A exemplifies Amphion’s 25-year commitment to advanced acoustic design, top-quality component selection, and pure signal path while providing a uniquely Amphion twist to the perks of an active monitor design. Despite its compact size, the One 25A is a powerful, full range monitor designed for the modern sound-making environment. The One 25A opens the door to not only recording studios, but also commercial studios, educational facilities, post-production, classical recording, and screen music compositions that require true full range.


Listening for impact, designing for results

Amphion’s dedication to honest and impactful audio and innovations in cabinet construction, driver selection, and crossover design have made them favourites of engineers and producers the world over including Jacquire King, Josh Gudwin, Mike Dean and Finneas O’Connell. This singular dedication to representing sound in ways that move the heart as well as the head similarly impacted the approach to the design of One25A.

As with all Amphion monitors, One 25A’s unique approach starts with its cabinet design. The compact monitor utilises an innovative sealed dual cabinet with isolated bass and midrange chambers to minimise acoustic cross-coupling and provide superior resolution and clarity. The baffle around the midrange chamber is acoustically symmetrical for a smooth frequency curve and precise imaging, and the design also incorporates the 5th generation of Amphion’s proprietary U/D/D (Uniformly Directive Diffusion) into the speaker for improved driver integration and speaker performance. Resonance and energy transfer are also optimised in the hexagonal bass cabinet design for a rich bass response that feels impactful, but precise. The result is a tight, tuneful reference monitor with all of the speed and accuracy users have come to expect from Amphion.


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, One 25A’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 maximises dynamics, resolution, and emotional transfer.
