Congratulations
on
your
purchase
of the
THIEL model
CS2,2
loudspeaker system. It is
the
result
of a lon-e
and dedicated
eflort to
provide
verv
accurate
music reproduction. We have used
only the
highest
quality
components
and taken
great
care in its construction. Properly
set
up and used
with good
associated
equipment,
the
CS2.2s
will provide
vou
with
a
great
deal
of
musical enjoyment
for
many
years.
Speaker

The
CS2.2s

I'HIEL speakers should usually be

fnrthcr apart than

is
usually achieved
when the speakers and th,: listener form an equilateral triangle. although this will

Aiming:
We
usually
pref'er
the
imagin-e
obtained
when
the
speakers are
pointed
straight ahead rather than
pointing
toward the
listener. This
placement produces
the
largest. most rratural
soundstage
However. toeing the speakers in somewhat rnay
produce
more specific
placements
of instruments. Also,
if it is
not
possible
to
.cet
the speakers
far enough
away
from
the sicle
walls,
a toed-
in
position
can
be helpful to reduce the strength of
wall reflections.
Bass:
Bass response is also afl-ectecl by speaker
placement.
In
generirl. when
a speaker
is close
to a
wall
the bass
response is
stl'onger ancl
placing
a speaker in a corner will make it even more so.
ln
order to achieve
properly
balanced bass.
it is necessary
for the speaker to be used
in the environment lor
which
it
was
designed. THIEL speakers are designed to
provide
accurate bass
when
positioned
away
fiom
all
walls-the same
position
that
provides
the best imaging.
Listener
position:
The CS2.2s
provide
broad dispersion of energy at all
frequencies ancl therefbre
provide good
results
throughout
a large listening area.
Best imaging is
provided
fbr
a

speakers.

Connecting
the Speakers
The CS2.2's
input ten.r.rinals are located on the bottom of
the speaker. To
gain
iiccess to
these
the
speaker should be
laid on its back or side.

tight.
It is essential
fbr
proper perfbrmance
that both speakers
in
a stereo
system be
wired
in the same
polarity.
The
speaker's input terminals are
color
coded
to facilitate this.
The wire
connected
to the red input terminal of each
speaker should connect
to the respective
positive
output
terminals of the amplifier: the
wire
connected
to the black
input tenninals
should be connected to the
respective
negative output terminals of the amplifier.
The speakers should be connected to the
amplifier with
high
quality
cable
to ensure minimal loss of
power
and
proper
control by
the amplifier. lf the speakers are being
connected to a
vacuum
tube
amplifier
with various
impedance taps,
the
ul
ohm tap
will
usually
give
the best
results.
