The Science of Sensation

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.

Coherent Source Transducer

When tweeters and midrange speaker drivers are mounted on a traditional flat baffle, the acoustic centers of the drivers are not aligned. The center of the midrange driver is positioned behind the baffle and the center of the tweeter is placed in the baffle’s plane. Some manufacturers try to resolve this problem with a stepped baffle, 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.

Precision Curve

In traditional speaker systems, several speaker drivers are aligned on a flat front baffle. 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 baffle 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.

Slant Layout Enclosure

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.
