Congratulations
!
You
are
now the
proud owner
of
a
Pioneer
R-series speaker
system,
To
make
full
use
of
its
astounding
potentials
and
to
avoid
errors
in
its
placement, connection and operation,
please
study
the
following instructions carefully.
ABOUT THE PIONEER R.SERIES
With the new
R-series,
Pioneer
introduces
a
new
concept
in
speaker
system design: the
individualistic
speaker. Even
at the
first
glance, these speakers
look
different, with their two-part front grilles
and
powerful-looking,
massive enclosures.
But
connect
a
pair
of
Pioneer
R-series
speakers
to
a good
stereo
amplifier, play
a
pro$am of
rock,
jazz
or
folk
music,
and
you'll
realize
that
these
speakers
are different.
We've designed
them
with
the
emphasis
on
impact
and
richness
rather than on laboratory
data.
That's what
makes Pioneer
R-series speakers
so
ideally suited
for
modern
music
while
also
lending
a
new feel
to
the
classical
repertoire.
THE
SOUND
OF
..LIGHT
POWER"
Compared
with
conventional
designs, Pioneer
R-
series speakers
sound
somewhat brighter and
at
the
same
time richer.
This
effect
was
achieved
by
a
care-
fully
selected
and
tested
combination
of
numerous
factors:
selection
of
special
material
for
the
woofer
cone,
balancing
of
the
different
speaker
units,
selec-
tion of
crossover
network
constants,
adoption
of
the
bass
reflex principle
in the
enclosure
-
without,
however,
causing
that notorious
"boominess"
of
bass
reflex
constructions.
CAREFULLY
BALANCED
BASS
REFLEX
DESIGN
In
a
bass
reflex
system
(in
which the
sound
waves
from the
rear side
of
the
woofer
are
reflected,
re-
versed
in
phase and
radiated
to
the
front
through
a
special
port),
careful selection and balancing
of
the
speaker
units
and
of
numerous
other
design
para-
meters
is
extraordinarily important.
In
the
Pioneer
R-series,
a
partition
of
sound
absorbing
material
is
provided
in
the
enclosure,
preventing
mutual
inter-
ference
of
the
speaker
units
and avoiding "standing
waves."
This
and the careful
dimensioning
of
the
port
lends these speaker systems
their
crisp
bass
re-
sponse.
What
seemed
to
be
impossible has
been
realized:
speaker
sound
that
is
momentous
without
being
boomy,
modern
without
being
untrue
to
the
original.
