In our eternal quest to offer you unrivalled sound perfection, we have taken innovative design further than ever before. In sound
perception, every element must be considered. Even the slightest detail can make a world of difference. With an ideal system, all sounds
produced by the loudspeakers arrive at the listeners’ ears simultaneously. If that doesn’t happen, the feeling of truly aligned performance
is lost. The effect is even worse in multi-channel systems, where the impression of being immersed in the performance space disappears.
Pioneer has developed the perfect answer: Perfect Time Alignment Design. This revolutionary 5-channel solution takes you as close to
the sensation of sound perfection as you will ever get.
The Science of Sensation
When tweeters and midrange speaker drivers are
mounted on a traditional fl at baffl e, the acoustic
centers of the drivers are not aligned. The center
of the midrange driver is positioned behind the
baffl e and the center of the tweeter is placed in the
baffl e’s plane. Some manufacturers try to resolve
this problem with a stepped baffl e, however this
results in unacceptable diffraction and coloring of
the sound. TAD cleverly opted to mount the tweeter
in the center of the midrange cone, which not only
optimizes sound propagation in all directions, but
also guarantees time alignment of the drivers.
Coherent Source Transducer
In traditional speaker systems, several speaker drivers are aligned on a fl at front
baffl e. Because the sounds from each driver reach the listener from different
distances, this composition inevitably leads to a small degree of confusion in the
overall sound. With Pioneer’s EX Series, a revolutionary baffl e with a precise
curved surface has been realized to solve this problem. This is the “precision
curve.” By positioning the speaker drivers on a three-meter radius sphere centered
on the listener, the time it takes for the sound to reach the listener’s ears from each
of the drivers is precisely adjusted.
Precision Curve
Enclosures have a backwards slant of eight degrees.
This brings the speaker’s center gravity of the
speaker directly over the center of the base of the
speaker. This positioning ensures stability of the
cabinet and freedom from the effects of speaker
vibrations. In combination with the Precisions
Curves, perfect time alignments of the drivers and
at the listening position is guaranteed.
