Amphion One18X Passive Studio Monitor

The One18X represents the evolutionary advancement of Amphion’s revered One18 modern workhorse monitor. A state-of-the-art 1-inch titanium tweeter and newly engineered crossover enhance clarity, resolution, and transient precision beyond its predecessor. This two-way passive radiator design combines highly linear, ultra-low distortion high-frequency reproduction with a 6.5-inch aluminum woofer for unprecedented detail and perfect spatial cues. The 1600Hz crossover point allows point-source operation for industry-leading phase coherence and pinpoint imaging, while the waveguide time-aligns driver voice coils for improved timing properties. DSP-free acoustic design minimizes electrical clutter, allowing full utilization of modern signal processing and room correction software. Extending from 45Hz to 55kHz, the One18X delivers clear, memorable monitoring even at lower volumes with even dispersion beyond a single sweet spot. Handmade in Finland, the One18X preserves its iconic status as a well-translating nearfield while raising the benchmark for trusted studio monitoring.

Key Features:

• State-of-the-Art Titanium Tweeter: 1-inch highly linear, ultra-low distortion design delivers unprecedented detail, extended frequency response to 55kHz, and perfect spatial cues for accurate stereo imaging.
• Newly Engineered Crossover: Enhanced design improves clarity, resolution, and transient precision while maintaining the 1600Hz crossover point that enables point-source operation and industry-leading phase coherence.
• Point-Source Design with Time-Aligned Drivers: Lowered crossover point and waveguide voice coil alignment create pinpoint imaging and phase coherence that translates precisely to any playback device across width, height, and depth planes.
• DSP-Free Acoustic Purity: Advanced acoustic design without digital signal processing minimizes electrical clutter, allowing full utilization of latest signal processing devices, room correction software, and other advanced tools.
• Industry-Leading Translation: Exceptional phase coherence and imaging ensure mixes translate accurately across playback systems, building confidence and productivity while meeting tight deadlines.
• Extended Low-Frequency Response: Passive radiator design with 6.5-inch aluminum woofer delivers flat response down to 45Hz for accurate bass reproduction in compact nearfield format.
• Even Dispersion and Low-Volume Clarity: Performs clearly and memorably even at lower listening volumes with even dispersion beyond single-seat sweet spot, ideal for challenging acoustic environments.
