DESIGN
FEATURES
The
BOSE
Model
301
Direct/Reflecting
loudspeaker
incorporates
several
features
that
make
its
operation
and
placement
different
from
other
loudspeakers.
The
exceptional
performance
of
the
Model
301,
to
a
great
degree,
can
be
attributed
to
Asymmetrical
Design,
the
Direct
Energy
Control,
and
a
Dual
Frequency
Crossover
Network.
ASYMMETRICAL
DESIGN
The
Asymmetrical
Design
of
the
Model
301
provides
a
high
proportion
of
reflected
sound
at
high
frequencies
and
contributes
to
the
exceptionally
spacious
stereo-
phonic
reproduction.
To
provide
balanced
spatial
properties
in
stereo
reproduction,
the
Model
301
stereo
pair
is
designed
so
that
the
speaker
used
on
the
left-hand
side
of
the
room
(this
speaker
is
called
“Part
1”)
is
a
mirror
image
of
the
speaker
on
the
right-hand
side
(this
speaker
is
called
“Part
2”).
The
Asymmetrical
Design
and
mirror
image
construction
of
the
Model
301
are
shown
in
Diagram
1
(page
5).
The
tweeters
direct
most
of
their
energy
toward
the
side
walls
of
the
room.
The
side
walls
reflect
high
frequency
energy
uniformly
throughout
the
listening
area,
resulting
in
a
stereo
image
extending
from
one
wall
of
the
room
to
the
other
(Diagram
2,
page6).
The
advantage
of
this
design
is
that
minimum
reliance
is
placed
on
the
rear
wall
of
the
room
for
providing
reflections.
This
maximizes
the
flexibility
of
placement
of
the
loudspeaker.
DIRECT
ENERGY
CONTROL
This
control,
located
at
the
top
of
the
cabinet,
allows
you
to
select
the
proportion
of
direct
to
re-
flected
sound
at
high
frequencies
to
produce
the
optimum
spatial
characteristics
for
your
particular
room.
If,
for
example,
the
side
walls
of
the
room
are
absent,
too
far
away,
or
covered
by
absorbing
material,
'
the
control
can
be
set
to
provide
predominantly
direct
sound
at
high
frequencies.
A
predominance
of
direct
sound
results
in
a
stereo
localization
of
sounds
primarily
to
the
area
between
the
two
speakers.
Sometimes
this
more
“inti-
mate”
sound
is
preferred
for
soloists
and
small
groups.
If
a
reflecting
side
wall
is
present,
and
a
more
spacious
sound
presentation
is
desired
(such
as
for
an
orchestra),
the
control
can
be
set
to
provide
a
larger
proportion
of
reflected
sound
at
high
frequencies.
This
results
in
sound
that
actually
extends
beyond
the
spacing
of
the
speakers.
DUAL
FREQUENCY
CROSSOVER
NETWORK
Contrary
to
tradi-
tional
design
philosophies,
the
crossover
network
of
the
Model
301
deliberately
overlaps
the
response
of
the
woofer
and
tweeter
by
over
an
octave,
and
adjusts
the
amplitude
and
phase
response
of
the
woofer
and
tweeter
to
provide
exactly
complementary
*Any
surface
that
feels
hard,
such
as
wood,
glass,
wallboard,
plaster
or
brick,
is
a
good
reflector.
A
soft
surface,
such
as
acoustic
tile,
drapery,
or
upholstered
furniture,
will
absorb
sound.
