This problem happens not only between the same
speaker models but also between the different
speaker models.
For example, in a live concert, it is common to
make speaker arrays using the multiple same
speaker systems. However, in a facility, it is
common to use different speaker models together.
Yamaha thought that "even if different speaker
models are used in a system, we should offer a
"white canvas" and paid attention to the phase
characteristics, aiming for the unification of the
phase characteristics through the series. As for
sound quality, we aimed for both the clearness of
speech (PA) and the high-fidelity sound
reinforcement of vocals/musical instruments,
while the unification of the tone color (Family
Sound Concept) of all products in the series was
the basic concept.
Also , we made a great effort to reproduce the
natural dimensions of the sound image.
In other words , the size of image must be an
accurate representation of the source , particularly
with regard to speech. In short, the design
concept of the "Installation" series is to realize the
concepts for the phase characteristics and tone
color.
The following explains the details of our concept,
as well as how to realize the concept.
2 Consideration of speaker
phase characteristics
In a design of “the installation series”, we
investigated the influences of phase
characteristics of speakers into their responses at
receiving points at first.
