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.
