Description
Introducing the Amphion One18, a superior addition to your studio recording gear. Renowned for its transparent and un-hyped sound, the One18 offers an unparalleled listening experience. This high-end passive monitor integrates a custom-designed 6.5" woofer, a fast-response titanium tweeter, a high-density Corian waveguide, and a sealed enclosure with a passive radiator to deliver the natural sound essential for your critical mixing decisions.
The passive design of the One18 offers a distinct performance advantage. By keeping sensitive electronics away from magnetized moving drivers, overall monitor functionality is improved. This design also enables you to choose an amplification solution without constraints on enclosure size or overheating concerns.
The One18's Corian waveguide is another defining feature that controls and balances the sound. It enhances the tweeter's ability to couple with the air, extending down to the 1.6kHz crossover point and ensuring uniform system dispersion across a wide frequency range. This physical alignment of the drivers significantly improves time and phase coherence, resulting in a solid phantom center, pinpoint imaging, and an extra wide and deep sweet spot.
