Know before you buy
The One18X features an updated tweeter and a redesigned crossover. These refinements provide improved clarity, higher resolution, and more precise transient response compared to the original model.
Because the One18X is a passive monitor, you will need a high-quality external power amplifier. Amphion recommends using an amplifier that can provide clean, stable power to ensure the speakers perform at their full potential.
Yes, the One18X is specifically designed for nearfield applications, making it an excellent choice for smaller rooms. Its waveguide design ensures pinpoint imaging and phase coherence, which helps the speakers perform accurately even when placed in tighter acoustic environments.
The absence of DSP means the signal path remains purely analog, avoiding the latency and potential artifacts introduced by digital processing. This results in a more natural, transparent sound that remains consistent even when you are monitoring at lower volumes.
Amphion monitors are widely recognized for their industry-leading translation. Because they prioritize phase accuracy and a natural frequency response, mixes created on the One18X tend to sound consistent across a wide variety of consumer playback devices.
By setting the crossover at 1600 Hz, Amphion keeps the most critical midrange frequencies within the reach of the woofer. This design choice minimizes phase issues and ensures a seamless transition between the drivers, contributing to the speaker's signature point-source sound.
