Description

The Amphion One18X is a two-way passive studio monitor crafted for precision, clarity, and consistent performance in professional audio environments. It delivers accurate sound reproduction with a natural sense of depth and space, making it suitable for critical listening tasks in music production, broadcast, and post-production work. Its clean, detailed response helps maintain confidence in mixing decisions across a variety of studio setups.

This model features a 6½'' aluminium mid/woofer and a 1'' titanium tweeter, paired through a carefully tuned waveguide for seamless integration and focused stereo imaging. The passive radiator design supports tight, well-controlled bass and improved midrange detail, even when the monitor is placed close to walls. With an acoustically neutral character and wide, even dispersion, the One18X supports consistent results from one room to the next.
