Description
Meet the Amphion One15, an impeccable performer in studio monitoring. These high-end passive monitors are a part of every pro monitoring setup, designed to deliver natural, transparent, and un-hyped sound that enables critical mixing decisions. The One15 stands out for its custom-designed drivers, high-density Corian waveguide, and a sealed enclosure with a passive radiator. It's the speaker you'd choose when you want to lose yourself in your favorite music and enjoy a beautifully honest listening experience.
The passive design of the One15 offers better performance by keeping sensitive electronics away from magnetized moving drivers. This improves every aspect of the monitor, and does not force the choice of an amplification solution based on its ability to fit inside an enclosure and not overheat it.
The Corian waveguide provides control and balance by improving the tweeter's ability to couple with the air, extending down to the 1.6kHz crossover point, and making the dispersion of the overall system more uniform throughout a wide frequency range. This results in a rock solid phantom center, pinpoint imaging, and an extra wide and deep sweet spot.
Key Features:
- High-quality studio monitors designed for uncompromised performance
- 2-way passive construction with rear-mounted passive radiator
- 5.25" mid/bass woofer
- 1" titanium tweeter
- Power recommendation 20 to 100 watts
The One15's sealed cabinet design results in a dramatic improvement in midrange resolution and bass accuracy, while also loading the room in a more controlled and predictable manner. The Amphion One15 studio monitors truly offer an impeccable performance.

Setup and maintenance
