A quality audio
system must accurately reproduce a good three-dimensional
image, which requires accurate phase matching between drivers
within a speaker and the speaker cabinets themselves. However,
our hearing mechanism is extremely hard to trick, and a lot
more has to go right before we think we are 'there'.
For
example, all speaker drivers must have low distortion
and be perfectly time aligned with each other, frequency
response must be essentially accurate to within about one
decibel, crossover distortion and comb filtering effects
must be imperceptible, dispersion characteristics must
be right for the room, the cabinet must not add noticeable
coloration to the sound, and room effects must be minimal.
Before
playback, a lot of effort is expended to ensure that
the microphones, electronics and recording media sourcing
the signal from the original performance are essentially
transparent, and that the recording we are listening to
is sufficiently well produced to preserve the natural ambience
and spatial accuracy of the performance.
All
else being equal then, the 'being there' experience
is usually made impossible because even high-end loudspeakers
fall down in some of these critical areas. DEQX Calibrated™
helps solve these last hurdles that traditionally have
been almost impossible to deal with using analogue technology. |
