Amphion Krypton3X

We thank mastering engineer Tom Fine for reviewing the Amphion Krypton3X. The discrepancy between the positive listening results and the less-than-optimal measured performance seems particularly large in this case. We believe that the way the measurement was conducted, along with Krypton’s size and somewhat uncommon midrange dispersion characteristics, played a part in this. While a small loudspeaker might possibly be measured at 1m, a loudspeaker as big as the Krypton3X is a different story.

"A working 'rule of thumb' for determining the boundary between near-field and far-field is to make the minimum measurement distance the longest dimension of the loudspeaker multiplied by 3." The Krypton3X is 1440mm, or 55" tall, which creates an optimal (minimum) measuring distance of 4320mm, or 165", which is radically longer than 1m, the measurement distance used.
