Despite its compact size, the One25A is a powerful, full range monitor designed for the modern sound-making environment. The One25A 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. 

As with all Amphion monitors, One25A’s unique approach starts with its cabinet design. The compact monitor utilizes an innovative sealed dual cabinet with isolated bass and midrange chambers to minimize 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 optimized 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, 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.
