The brand’s dedication to honest and impactful audio and innovations in cabinet construction, driver selection, and crossover design have made them favorites of engineers and producers the world over. The same principles have applied to the design of the new One25A. Despite its compact size the new studio monitors are a powerful, full range design. The One25A opens the doors to not only modern recording studios, but also commercial studios, educational facilities, post-production, classical recording, composers for film — that require true full range.
The brand’s dedication to honest and impactful audio and innovations in cabinet construction, driver selection, and crossover design have made them favorites of engineers and producers the world over. 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.
"Some might be a bit surprised about introduction of an active Amphion product, but it must be remembered that One25A’s active 3-way high-resolution filter is simply a natural progression from the active 2-way filters that we have utilized in our Base systems since 2015. Our design philosophy has always been results- not technology –oriented. So, we use whatever approach we feel works best for a certain product,” explains Amphion CEO Anssi Hyvönen.
As with all Amphion monitors, the One25A's approach started 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 to improve the bass response. The result, the company says, is "a tight, tuneful reference monitor with all of the speed and accuracy users have come to expect from Amphion."

The choice of drivers included a 1" titanium tweeter, a 5.25" aluminum midrange, and a generous 10" woofer for the low end, with crossover points at 100Hz and 2000Hz.
"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," they add.
In terms of the added electronics of an active monitor design, the One25A monitors are matched with amplifiers with enough power for all intended applications, including music creation, film and TV scoring, and audio post-production. The amplifier delivers 700W to the bass range, with 2 x 205W for the tweeter and midrange. The electronic components are located on the exterior, well isolated from the speaker enclosure, not only to improve performance but to ensure long life and easy serviceability as well as adaptation to soffit mounting.

"At Amphion we have learned that recreating the beauty and emotional impact of sound takes more than just chasing the latest technology – and that listening is big part of our development process," says Hyvönen. "We’re thrilled to bring One25A to the market and proud to have it alongside our existing monitor lines as another way to experience the difference Amphion can make to your workflow."
All Amphion products are built in Finland. The One25A three-way active studio monitors will be on display and can be experienced at Booth 15513, North ACC Hall, during the 2023 NAMM show. The new monitors are available for pre-order for $14,900.00 USD per pair. Shipping will begin on August 1, 2023.
