I'd rate this 11/10 if I could.

Gave 4.5/5 since I ordered a like new demo pair that should've been marked used instead of demo. Not sure what happened. The corners were impacted during shipping possibly. Sweetwater is making it right however as we speak. Highly recommended regardless. I placed them onto the stands and got to try them before shipping them back for a replacement pair.

These speakers are so overhyped on the Amphion Beautiful thread via Gearspace. So I told myself to not believe the hype, order a pair, and just try it out for myself. If it doesn't live up to my expectations or needs, I'd be returning them completely. I've been frustrated and fatigued with my mix cube and krk v6 combo. I generally think that pair is pretty great for home studio and my ears had adjusted to them so they translate decently now, however it took a lot of learning after coming from Yamaha hs5 that I was used to. I switch between a full range with Kirk sub 10in + v6 pair and mix cube as a midrange check. They served me well until now.........and NOW....Day 1 for Ampions, I got straight to mixing and was hyped about them for the first couple hours of working. After that, they sort of just disappeared and I forgot about that I was working on a brand new set. I spent the rest of the day working on projects in the queue....Next day, I check the mix on my phone and it sounds great! This is never happens on the first go. Imagine things will only get better from here. I believe it. Great translation.

If you are poor at getting tones, these speakers won't cure that - but they are honest. So if you trust your own taste, this Amphion One15 Pair will allow you to execute your vision through sounds...as you hear it in your head....as long as you hear it yourself, you can use this pair to help you along the journey.

Here is my favorite quote, posted 2018 by "Doc Mixwell":
I would say, these ONE15 have a really "opaque" invisibility to them...Extremely holographic. Open like an envelope with money in it. The wide center image has me intrigued.

I'm not doing much to tame the hype, but I like them so much that it's got me wondering what the two18 are like. Superb.
A friend told me these are fatiguing in comparison with PMC and ATC. These are definitely not fatiguing, but rich and honest in the midrange. I'm guessing their mix was fatiguing and these probably just did a good job of telling them so, rather than a feature of the speakers eq curve.

ALSO: These work better in untreated spaces more than any other speaker I've tried and will only improve after treatment. I would also check out the Amnion One12 if you find yourself in a tight space. I've paired this with the Behringer A800 and it works pretty well together. Good budget option.

Just decided to upgrade my monitors recently to the Amphion One15 pair as my Yamaha HS8s were too fatiguing and it was getting frustrating having to take so many breaks when mixing. These things are insane. It is truly mind-boggling how much low end comes out of these tiny speakers! Completely got rid of my subwoofer because I can accurately hear down to about 50hz on these bad boys! The overall clarity is outstanding. I"m hearing things in songs that I"ve never heard before. What used to get lost in the mush of traditional speakers can now be accurately pinpointed. Whether it be a quiet synth in the mix following the melody in a pop song, or just a weird reverb effect in the background, the One15s will show you exactly what is going on! They"re like a pair of sonic microscopes! Don"t think, just buy them!

One15's are an amazing tool for mix translation. I have never worked on any other speaker where what I make sound great in the studio translates so well everywhere else.

They are not capable of really loud playback, they are a mixing tool, meant for making decisions. If you need to run them loud, you'll want to add a sub, as the woofer will be the weakest link.

Honestly at this price they are one of the best values on the market. I have worked on lots of high end monitors such as ATC, Barefoot, Focal, etc to the old classics like NS10's . Some may sound more impressive than the Amphions, but they don't translate as well.

If you are looking for a really useful tool that will save you time and get you great results, this is the ticket. A nice bonus is that they are 1/5th of the price of the ATC's that I also really liked.

WIN!

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.

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.

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
