■ Passive Nearfield Monitor, 6.5-inch, Single Unit

■ Reduced Distortion and Improved Expansion
The One18X is the next generation of the wildly trusted One18.

A cutting-edge tweeter and newly designed crossover deliver improved clarity, resolution, and accurate transient reproduction. This reduces the discrepancy with headphone environments.

The highly linear tweeter and ultra-low distortion deliver unparalleled detail and perfect positioning. The One18X meets the performance demands of modern nearfield monitors while raising the bar for studio monitors.

■ Reproducibility
Being able to trust what you hear leads to confidence and improves the quality of your results and productivity. Amphion monitors allow you to focus on what's important, supporting production environments where time and deadlines are tight.

■ Pinpoint Imaging
Phase accuracy and high-precision reproduction enhance playback accuracy in any environment. This results in precise detail in all dimensions, including width, height, and depth.

■Pure Acoustics, No DSP Required
Amphion's advanced acoustic design minimizes electrical noise. Amphion's pure sound maximizes the capabilities of the latest processors, room correction, and other advanced third-party software.

■Point Source Sound
Lowering the crossover point allows the speakers to operate in point-source mode, resulting in industry-leading phase accuracy and pinpoint sound imaging.

■Time-Synchronized Drivers
Waveguides align the tweeter and woofer voice coils to the same volume, improving the timing characteristics between each driver.

■High Sound Quality Guaranteed Even at Low Volumes
Minimally affected by installation position, the speakers perform excellently even in challenging acoustic environments. They deliver clear sound quality even at low volumes. Uniform sound dispersion allows for a wide listening point.
