"Has to be heard to be believed."

"The first thing I noticed was the immediate improvement on the stereo image compared to the monitors I’m currently using, the clarity of the Amphion speakers has to be heard to be believed."

“These are amazing workhorse monitors."

"These are amazing workhorse monitors that are detailed, full, and pleasant to work on. What an awesome sound it is! I’m not sure that I want to mix without them..."


"The next NS10”

"To get a solid handle on how beautifully honest the One18 is, you must audition a pair as soon as possible. I assure you your mixes will translate."


"Excellent speakers!"

“I can mix comfortably, sitting anywhere around the console. The natural tone and frequency response allowed me to achieve 12-hour-long sessions, with no fatigue. Excellent speakers!"

"I hear everything"

"I don't understand how I ever managed without these. I used to spend 20 hours on a project. Now I achieve the same in 6-8 hours! I hear everything!"

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.
