The Amphion One12 is an extreme-nearfield studio monitor designed for professional audio work wherever space and acoustics are challenging. Built for studio and mobile use alike, One12 monitors minimize the influence of the room, allowing you to focus on pure, honest sound rather than reflections or coloration from the environment. It is ideally suited for home studios, small postproduction edit bays, mobile trucks, and FOH applications where accuracy and compact size are equally critical. Sonically, the One12 delivers the detail and comfort of high-resolution headphones, while still allowing the entire production team to share the listening experience.
Critical Technical Details
The One12 is a two-way passive radiator nearfield monitor featuring a 1" titanium tweeter and a 4.5" aluminum woofer. A 1600 Hz crossover point supports point-source operation and phase coherence, while time-aligned drivers ensure accurate transient response. The monitor delivers a frequency response of 78 Hz to 20 kHz within ±3 dB. Recommended amplifier power ranges from 50 to 200W. The cabinet measures 10.19 x 5.2 x 8.66" and weighs 11 lb, making the One12 easy to place in space-constrained professional environments.
Accurate Translation and Imaging
Trusting what you hear is essential for confident decision-making, and the One12 is engineered to translate reliably across playback systems. Its point-source sound and precise phase coherence enable accurate reproduction of width, height, and depth, helping mixes and edits carry over naturally to any listening environment. This accuracy improves workflow efficiency and supports consistent results under tight production deadlines.
DSP-Free Acoustic Purity
The One12 relies on advanced acoustic engineering rather than DSP, minimizing electrical complexity in the signal path. This approach preserves resolution and transparency while allowing external signal processing, room correction, and other advanced software tools to perform at their full potential. Amphion's proprietary 5th-generation U/D/D (Uniformly Directive Diffusion) waveguide further enhances driver integration and room performance.
Even Dispersion and Room-Wide Sweet Spot
Designed to perform clearly even at low listening levels, the One12 remains articulate and engaging without requiring high volume. Its even dispersion creates a wide sweet spot, making placement easy and ensuring that clarity and balance are maintained throughout the room and not just at a single listening position.
Tuned Passive Radiator Design
Instead of relying on reflex ports, the One12 uses a carefully tuned passive radiator to deliver controlled, natural bass from a compact enclosure. This design improves low-frequency performance and distributes energy into the room more evenly, resulting in a tighter and more realistic low-end response.
