Naturally Uncompromised Sound

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.

Amphion One15 Monitor Speakers at a Glance:
  • A beautifully honest listening experience
  • Better performance from passive design
  • Corian waveguide provides control and balance
  • Point source performance - no audible crossover point
  • Sealed box + passive radiator = much greater accuracy
A beautifully honest listening experience

Many studio monitors are great to work on, but not necessarily the speakers you'd choose when you want to get lost in your favorite music. Amphion professional studio monitors are designed with the ultimate goal of providing a "beautifully honest" listening experience that makes tracking, mixing and mastering not only easy...but really enjoyable as well.

Better performance from passive design

Simply put - better performance. Keeping sensitive electronics away from magnetized moving drivers 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.

Corian waveguide provides control and balance

All Amphion monitors feature a fifth-generation waveguide CNC machined out of high density Corian. This improves the tweeter's ability to couple with the air, helping it to extend down to the 1.6kHz crossover point and making the dispersion of the overall system more uniform throughout a wide frequency range. It also physically aligns the drivers, which improves the time and phase coherence tremendously. The result is a rock solid phantom center, pinpoint imaging and an extra wide and deep sweet spot.

Point source performance - no audible crossover point!

Driver integration is one of the main challenges in speaker design and construction. The goal is to achieve a single point where the acoustical centers of the driver combination can work together perfectly, just like what happens in real life. If you want to combine two different audio signals as seamlessly as possible, doesn't it make sense to place the seam outside the most sensitive areas of the hearing range? Human hearing is not linear. The ear's sensitivity is highest inside the critical middle of the hearing range, generally located between 2-50kHz. Employing an unconventionally low crossover point allows the use of drivers with the lowest possible moving mass in the range where the ear is most sensitive, resulting in an unprecedented amount of midrange clarity and depth, and a single point source/phantom center image typically only found in coaxial designs.

Sealed box + passive radiator = much greater accuracy

A ported box always has uncontrolled pressure changes and turbulence inside the cabinet which lead to decreased resolution - especially in the midrange - preventing a balanced audio signal from being reproduced optimally. 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. Essentially a speaker cone, surround and basket without the motor, Amphion's rear-mounted passive radiator moves in perfect synchronization with the front woofer, ensuring that the distance from the front of the cabinet to the rear is always the same and that the balance of air in the cabinet is maintained. This results in a much tighter, even response in the low end of the spectrum, guaranteeing more accurate translation to just about any playback system. A passive radiator is not the same as a rear port, and is nowhere near as sensitive to placement near a rear wall.

Amphion One15 Passive Studio Monitors 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
Amphion One15 studio monitors offer impeccable performance.

UNREAL sound. Crystal clear.

Incredible, beautiful, transparent, highly imaged, detailed sound. Everything else sounds like mud, now. I need more power, so I might get a sub, or go one notch up in size. I like it loud and detailed, but softer, these don't lie.

Very Nice

Bought a pair with a 100w amp. Had improved acoustic treatment in my room with good results and replacing the mackie nearfields I had with these was a dramatic improvement again. They give better test results particularly in low mids but also noticeable improvements over 6k. I also notice they give better depth perception and seem to improve my ability to dial in a mix as the mixes are more accurate when I check them for translation in other locations. One thing in particular that I'm very pleased with is that I was checking them using some of my own typical reference mixes and was able to hear things I never noticed before. One that comes to mind is a particular delay throw on a guitar duet that I've been using as a reference track for about 20 years. The only downside is the cost.

O.M.G

I was looking for monitors that would let me hear my top end ad/da converters at their best cause we all know top convertors with mid level or low budget speaker don't really let you hear what you paid for. So many people told me focal,adams,genelecs,etc.. I heard all these speakers before & the one's that stood out was Equator Audio & Adams but then a friend of mine was having a shootout with the best speakers money can buy ATC20's,PMC's two two's, Barefoot 27,PSI 17,Event Opals,Focal sm9's/solo6, Amphion 18. Now that's high end and you couldn't go wrong with any of them cause at this level it's more your personal preference than the monitors. My top 5 was ATC,PMC,PSI, Amphion & Barefoot. So i called sweetwater for the PSI and they said PSI already had a exclusive dealer in the U.S. but than i got a call back saying they just got a deal with Amphion so i told my rep send me a pair of one15's. Now let review them I had a session with a hip hop client so it was a great chance to review the low end, the one15's was accurate down there sweet & true w/o the lows of bass they actually surprised me with the amount of bass they put out , the mid & highs had me my assistant engineer & my clients looking at each other in disbelief that's monitors can sound that good straight out the box. I was told by the rep from Amphion to play them for 50 hours than i would truly get the best out of them & boy he was spot on this is the way music is suppose to sound. Look do yourself a favor if you truly want to hear what your recording or mixing get a Pair of Amphion Oh by the way they translate exceptionally well

I have used these Amphion speakers in my acoustically treated studio and they have quickly become my favorite speaker. I've been mastering for eight years now and engineering for over 20 years, and these are the best speakers that I've ever heard. I love the clarity of these Amphions, the phase response is the best of any speaker I've ever tested in my studio. It has never been so easy for me to hear what needs to be done with a mix to make it sound great! Do yourself a favor and get these speakers with the Amp 100 and the speaker cables, they are a big part of why I love this speaker system.
