Stabilize.
Pins
Spea-kers
posilioned
on a soft surface such as carpeting or an
uneven su.face are able to rock back and forth
slightly and
will vibrate in reaction
to those forces ihe speaker
generates
to move
the driver diaphragms.
(Every
action has
an equal and
opposite
reaction.)
This motion of the speaker causes a loss
of musical infonnation and reduces rhe clarity
of the music.
In order to eliminate this effect, the THIEL CSI.2
can be used with the included stabilizer
pins.
The
srabilizer
pins,
either
of two typ€s, are
pushed
into thr€e
pre-dr;lled
holes in
the base of each speaker The
poinied pins
are
for
speakers thar will be
placed
on carpet. The
point penetrates
rhe carpet
and allows the speakerto r€si firmly on the floor.
The rounded slabilizer
pins
are for speakers ihat are
placed
on a
hard,
uneven surface. The three
pins provide
a stable
foundation which el;minares
some obscuring ofinlbrmalion and
produces
a cleane.,
more articulate sound.
Th€re are some applications where
the stabilizer
pins
will not bring an irnprovement
in sound but may actually make
it
worse. This siruation
occurs
when
ihe floor itselfis nor rigid and therefore vibrates when
conneded to ihe speakers via
the
slabilizerpins. We encourage you
to experiment to derermine for yourself whelher
or not this is ihe case.
We recommend
lhat
you
determine the
position
ofyour speakers
before insening ihe
pointed
srabilizerpins. To
insert the
pins,
rih the speakerforward
and
push
the iwo back
pins
fully into the 1
'deep
holes
located in each back cornerofthe
plinth.
Then rock the sperler
backwafd and insert the fioni
pin.
Finally.
press
fimly
on the top ofthe speaker with a
slight rocking
motion untilthe pins penet.ate
lbe carpet complerely. To check that lhe pins
arc firmly seated,lighily iap the
back and side of
the speaker. There should be no movem€nt and the speaker
should f€el solidly in
place.
lfthe speaker is moved with
the
p;ns
in
place,
care should be ialen to lifl
the speakers straight upward until allthe
pins
have cleared the
carpel. Also, tilting the speaker so its weight is resring
on any single
pin
can damage ihe wood
base.
Please
be cautioned that the
pointed pins
can be dangero
s if ot used with carc. TheJ can ca se sma

and it is
possible
to damaqe carye^ if the speikers

Associated Equipment
The
CSI.2 is a
very
high
quality
sound reproducer and will
benefit
from
use with the best associated
equipment. Since ir is
extremely accurate. it will reveal sources ofdistonion generared
elsewhere in ihe system. For
example. distortion resulring
from cartridge misalignrneni or inferior
electronics
will
be reproduced accurarely. Also, the
quality
ofthe interconnecr cables
and
spealer cables
will
significandy effect the
performance
oftbe
sysrem.
Power Requirements
It is imponant to have
enough
power
to
play
at the level
you
desire without
distortion. Ifhigh sound l€vels are
desired. the
CSl.2s are des;gned to be used with amplifi€rs rated up to 150 watts
per
channel. If
you play
ihe speakers more loudly
rhan
the volume the amplifiercan cleanly
produce,
the arnplifief willproduce
overload
(clipping)
distonion.
The sound witl
become comprcssed, slrained, and in
extreme cases. obviously disrorr€d. This dislonion is
actually non,musical u.hlititrt
€nery) and since
it
is concentmted in the bigh fiequency region where
the speaker is least able io handle ir, rweeters
can be
damaged in extreme cases.
Keep in mind that sound
qraliry
is usually much more imponant
than sound
qrdrriry.
There can be large differences
in rhe
sonic
perfonnance
of two amplifiers ofequal
power
which
are
more important
than a large difference in
power.
Almosr
everybody will
be
happier with
a 50
watt
amplitier ofhigh sonic
quality
rhan
with
a 200
watt
amplifier of mediocre
sonic
quality.
Forthis reason, we
feel there is no subsiiture for listening to make your
amplifier decision.
The
question
"how
much
power
do I need?" does not have the
simple answer most
people
expecr because ir ;!
not
determined only by the loudspeaker's efficiency, but
also by the
volume
desired and the size ofthe room. Ifall
tbree lactors
are average. aboui 50 watts
per
channel is required.
Each factor can raise or lower this amount
by about three rimes.
1) A spealer with a low efficiency
of 84dB,AV,m
willrequire
twice the
powerofan
average
87dBA
-m
speaker and onc
with
a high mting of
godB,Aff'm
willrequne only hall the
power
ofan average speaker. Usually, high efficiency
caD be
obtained only by trading off sonic
quality-there
are very few
spealers that
prcvide
a
very
high level of both. The
CSI.2 is
of average efficiency
(87dB)
and therefore requires a normal
amounr of
power.
2) Usually,
people
who "don't like music loud"
can decrcase their
power
io about one-half. Also,
people
who
like music
loud should increase their
power
by 2 times
or
more.
Most
people
fall within a normal range.
3) A small room will need less
power
for a
g;ven
loudness
level than a large room. A very srnallroom
of 1000 cu fr
(l1
x
l 1
'
with an 8' ceiling) will usually requ;re
only half the
power
of an average size room. A large
room of 6000 cu ft
(20
x
30
with a l0'ceiling) will
usually
require
twice the average
power.
lf the listening room is
connected to another room by a large
open area, the required
power
will
increase, but not by tbe amount ofthe combined room volume.lfrhe
room has a
"dropped"
ceiling
w;th I;ghtpanels,
the ceiling will be almost transparent acoustically
and the space above the ce;ling
should
be added.lfthe
panels
are heavy they will act as a more normalceiling.
With
all this in mind. a
p€rson
who doesn't like ro
play
rnusic
very
loudly and has a small room can
get
high quality
sound
with
only 20 watts whereas a
person
who sometimes likes
to
play
loudly and has a large room may need
150
wans.
