Any pro monitoring setup could benefit from Amphion One15 speakers. These high-end passive monitors employ custom-designed drivers, a high-density Corian waveguide, and a sealed enclosure with a passive radiator to deliver the natural, transparent, un-hyped sound you need to make critical mixing decisions.

"Kompromisslos abgestimmt"

"Man verbringt wesentliche Teile der Arbeitszeit an einem Projekt im Nah-feldbereich. Das verlangt nach einer verlässlichen wie schonenden Abhörsituation am Regiearbeitsplatz. Der finnische Hersteller Amphion bietet mit den One15-Mo- nitoren und ausgezeichnet abgestimmter Amp100-Ver- stärkung eine Kombination, die derlei Anforderungen und professionellen Ansprüchen vollauf gerecht wird."


"Escoge un par basado en tu cuarto y tus necesidades y estarás contento. "

"Al igual que con las demás bocinas Amphion, no hay nada fatigante en los agudos, y el Two15 es lleno y placentero en una manera nada exagerada. ."


"Delightfully detailed realism..."

" If I was going to go with a single set of monitors for my room, I am pretty sure I would go with a pair of Two15 speakers and an Amp500.."


"They do the fundamental job of communication really well."

"The One15 doesn’t sound overly ambitious with its low-frequency extension, so there’s no obvious time-domain problem. It helps, of course, that, being free of a reflex port, there are no chuffing noises or obvious non-linearity, or one-note bass effect when the volume is increased."


"If you demo a set in your room, it's very likely you'll keep them."

"These monitors perform well above their price range and are an incredible value for such refined tools, arguably one of the most critical tools for mixing. The mixes I complete on them are translating well to other rooms and playback systems, and I'm producing the best work of my career."


"I make better decisions faster."

"Every tool I keep and use daily is a tool that either helps make my final product better or helps me work faster; the One15's do both. I immediately noticed  how much quicker I made choices with tones and instrument placement. I make better decisions faster."

Record Producer/Songwriter

"The resolution is stunning."

"The time domain is where this speaker really shines. I have no other speaker (in any price range) that I know of that translates things like reverb and acoustics like these do. I have much more control over the reverb than I had with any other speaker."

Because all real control rooms have at least one surface (a floor) the speaker low end (below 100Hz) is measured in half free space. This gives a fairly accurate estimation of a very large control room, with the speaker placed far from back and side walls.  As the room size decreases, the amount of bass increases, which means that the smaller speaker models are particularly well suited to smaller rooms which will support the bass response of the speaker. In other words, the plotted frequency response corresponds to the minimum amount of bass you can expect in any control room.
