Micro Dynamic Capability: This describes the ability of a system to
resolve the lowest level material with as much articulation and imaging
as it does at the louder levels. The most difficult areas for loudspeaker
systems to reproduce well are the extremes, i.e. the micro-dynamics
from ppp to p (pianissimo to piano), and the last part of the macro-
dynamics f to fff (forte to triple forte).
Imaging and Soundstaging: A reference system must be able to
recreate a deep, tall and wide soundstage with accurate imaging
when reproducing recordings that contain such information. The effect
is that of being able to clearly distinguish the specific locations
(left/right, forward/back, height) at which the instruments are playing,
and to be able to hear their performance from the perspective of the
venue in which it was recorded.
These concepts can be understood in a basic sense by examining the
temporal coherence of a loudspeaker system. If each frequency of the
audio spectrum arrives at the listener at the same time, spatial cues
emanating from a performance are reproduced, i.e. sound waves
bounced from the walls, floor and ceiling of the venue, attenuated in
amplitude and displaced in time, can be resolved in space by two
stereo channels. If a reference system can slice time “thinly enough”,
and have excellent low-level resolving power, one can experience
many such bounces off surfaces; all displaced correctly in time,
ultimately defining the soundstage.
Low Harmonic and Intermodulation Distortion: The greatest sound
pressure peaks should create almost no distortion whatever. Many
loudspeakers begin to experience signal compression at loud levels.
When this happens, music becomes distorted as sounds compress.
Reference systems cannot exhibit these symptoms. Just as live music
sounds relaxed at the loudest levels, so must the reference system.
