NOTE:
We do
not
mean
to
give the
impression
that
a
center
channel
speaker
is
normally
necessary
In
a
stereo
Installation.
We
consider
it,
rather,
to be
a
conven-
ient
facility
In the
case
that
the
channel
land2speak-
ers
have to
be
spread
apart
more
than
the
normal
8 to
10
feet,
or
that,
with
normal
spacing,
listening
at
close
quarters
Is
often
necessary.
Underfhese
circum-
stances
the
sound
from
the
channel
1
and
2
speakers
may
become
disassociated,
resulting
in a
phenomenon
known
as
"hole-in-the-middle".
The
center
channel
speaker
is a
remedy
for
this
situation.
