One15
Best accurate sound for critical audio production.
The Amphion One15 is a compact, passive, 2-way nearfield studio monitor designed for tracking, mixing, and mastering. It features custom-designed drivers, including a 5.5-inch aluminum woofer and a 1-inch titanium tweeter, housed within a proprietary Corian waveguide for point-source behavior and wide dispersion. A passive radiator enhances bass response without port noise, delivering natural, transparent sound. These monitors are praised for their trustworthy translation, accurate stereo imaging even at low volumes, and ability to reveal sonic details, making them suitable for both home and commercial studios.

Know before you buy
Yes, because these are passive monitors, they require an external power amplifier. We recommend an amplifier capable of delivering between 20 and 100 watts per channel to ensure optimal performance.
The passive radiator allows the One15 to produce deep, accurate bass without the air turbulence or 'chuffing' often associated with traditional bass reflex ports. This results in a tighter, more natural low-end response that remains clear even at lower volumes.
Absolutely. Their compact size and exceptional stereo imaging at low volumes make them an ideal choice for smaller rooms where you need high-end accuracy without overwhelming the space.
The Corian waveguide is designed to create point-source behavior, which ensures that the sound from the tweeter and woofer reaches your ears at the same time. This provides a wider, more consistent sweet spot and superior stereo imaging.
Yes, the One15 is widely regarded for its neutral and transparent tonal balance. Because the speakers don't hype or color the sound, you can make mixing decisions that reliably translate to car stereos, club systems, and consumer headphones.
