# Active full-range monitor One25A

Amphion One25A is a high-quality three-way studio monitor designed with all recording professionals' needs in mind. This model represents the culmination of 25 years of Amphion's experience in acoustic design, combining the convenience of active speakers with the purity of signal path typically found in passive speaker systems.


## Industry-leading sound reproduction

Having confidence in what you hear strengthens your workflow, delivers the best results, and enhances productivity. Amphion monitors allow you to focus on the essentials, saving time and helping meet tight deadlines.


## Transparent sound

With phase coherence and pristine sound reproduction, Amphion monitors accurately reproduce signals from any source. The One25A spreads sound faithfully in all dimensions, including width, height, and depth.


## Direct optimized signal path

Active speakers often suffer from insufficient resolution due to complicated signal paths. The One25A eliminates dynamic, detail-deteriorating DSP and AD/DA cascades, providing maximum resolution and performance.


## Isolated independent chambers

New midrange and high-frequency drivers are placed in an isolated sealed chamber that minimizes negative effects from the woofer, such as changes in internal pressure. This leads to high-resolution mid and high frequencies, delivering crystal clear transparent sound.


## Acoustic symmetry

The partition around the midrange driver is acoustically symmetrical, resulting in a smooth frequency curve and precise reproduction. Amphion's 5th generation U/D/D patented technology improves sound quality and speaker integration in the room.


## Removable amplifier block

Placing the amplifier inside the monitor negatively impacts the speakers. All electronics of the One25A are located outside in a rigid steel housing that can be removed for separate installation.
