A White Paper Of The Installation Series Loudspeakers
- Non coloration sound regardless of the total
level
- Same timbre at any position within the
directivity range
- Adequate audio image size of each source
(2) Family Sound Concept
For a facility in a hall, theater or church,
auxiliary speakers such as under-balcony
speaker and frontfill speaker may be used for
audience, in addition to the main speakers.
The sounds generated by these speakers are
mixed in the room/hall space. However, it was
very difficult to get the same timbre at any
position in the room/hall because the timbre of
each speaker is different if the size or model is
different (even though the manufacturer is the
same).
Now, Yamaha introduces "Family Sound
Concept". According to this concept, all
speaker models in the same series has the same
tone color.
- Unification of the tone color between the
different directivity models using the same
enclosure
- Unification of the tone color between the
passive and bi-amp modes of the same model
- Unification of the tone color between the
high-power and middle-power models using the
same enclosure
- Unification of the tone color between the
different enclosure models
(3) Minimizing the electronic compensation
The equalizing operation compensates the
amplitude response; on the other hand it causes
deterioration of the phase characteristics. The
more you compensate the amplitude response,
the more the phase changes.
So we aimed for minimizing the electronic
compensation using the equalizer.
Especially for the crossover range, we aimed
not to use the equalizer at all.
(4) Cooperation with an outside speaker
designer
We decided to design the speakers in
cooperation with an outside speaker designer.
The leader of the Yamaha speaker developing
team was Akira Nakamura. He was the
developer of the "NS1000M" long-seller hi-fi
speaker, the "NS10M" de facto standard
speaker in the studio and the "MSP series"
powered monitor speakers.
We appointed Mr. Michael Adams as the
outside speaker designer. He is not only a
veteran speaker designer but also has a long
experience as an SR engineer and currently he
is the chief designer of "Audio Composite
Engineering", a speaker designing company in
U.S.A.
He understood and Yamaha's concept that
seemed to be very difficult to make it realize.
He is one and only speaker designer who has
golden ears of an SR engineer.
