The Amphion One25A is the first 3-way active studio monitor design from the Finnish loudspeaker manufacturer. The One25A monitor exemplifies the brand’s 25-year commitment to advanced acoustic design, top-quality component selection, and pure signal path while providing a uniquely Amphion twist on the perks of an active monitor design. 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, the 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 fifth 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 the speed and accuracy users have come to expect from Amphion.

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.
