Many people know Yamaha as one of the
world's top manufacturers of home and
professional audio equipment, musical
instruments, and motorcycles. But what they
don't know is that we're also a leader in
acoustic research and technology, and in the
development and production of sophisticated
audio microprocessors. We were also one of

the first companies to embrace digital
technology, and have done much to make
digital audio as popular as it is today.

All of which means that we are ideally
qualified to produce the world's finest home
theater systems. With years of acoustic, audio,
and digital expertise to draw on, we have been
able to develop innovative, high-performance
home theater systems that make it possible to
enjoy movies at home with all the dramatic
sound impact that the director intended to
convey.

Now, in response to growing demand for a
home theater reference speaker system worthy
of the Yamaha name, we have developed the

Conventional Radiation
Waveguide Horn Radiation

Yamaha's goal in developing the HX Series speakers
was to achieve the three key elements of accuracy,
speed and depth, thereby creating a home theater
audio experience comparable to a real movie theater
or concert hall. This goal has been brilliantly realized
on the HX Series, assuring superb reproduction that
expresses every nuance of the soundtrack designer
or concert-recording engineer's intentions.

The Waveguide Horns

When conventional direct radiating speakers are
used in a home environment, their broad directional
characteristics result in a relatively high proportion of
reflected sound. Even at frequencies above 5kHz, a
significant portion of the sound reaching the
listeners' ears has been
reflected from the room's
walls.

Modern movie theaters,
however, are designed to offer
a highly absorptive acoustic
environment in which
soundtrack recordings with
five or more channels can be
used to achieve a rich sense
of spatial expression. To achieve a similar level of
spatial expression in the home, it is therefore
necessary to use speakers with a direct/reflected
sound ratio that is quite different from the speakers
used for listening to conventional music recordings.

Yamaha's exclusive Waveguide Horns were
specifically developed to address this problem, and
have now been refined and improved to offer an
even higher level of spatial expression in home

listening environments.

Optimal Direct/Reflected Wave Energy Ratio for
Home Theater Sound

Yamaha's exclusive Waveguide Horns differ from
conventional horns in that their waveguide features a
horizontal control angle of 135° and a vertical control
angle of 120°. This allows the sound field to be
shaped and controlled for optimal spatial expression
in home theater environments.

Diecast Aluminum Waveguides

Yamaha tested a wide range of waveguide materials
to determine which offered the best home theater
sound reproduction quality. Cherry and other
hardwoods were considered, but in the end, diecast
aluminum was found to make the detailed nuances
of dialogue easier to hear, while providing the
incisive attack needed for action and horror scenes.
