CONNECTING THE SPEAKERS
The CS3.6’s input terminals are located on the bottom of the
speaker. To gain access to them, the speaker should be laid on
its back or side. Make sure that all connections are tight.
It is essential for proper performance 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 terminals 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. If the speakers are being connected to a vacuum
tube amplifier with various impedance taps, the 4 ohm tap will
usually give the best results.

MANUFACTURED BY:
THIEL Lexington, Kentucky USA
Due to European CE regulations that do not permit banana
plug type loudspeaker connections, we ship THIEL speakers
with removable plugs installed in the ends of the binding posts.
If you wish to use banana plug type connections, you may
remove the black plastic plug inserted into the end of each
metal binding post cap. To remove the plug, use your fingernail
to pry along the bottom edge of the plastic insert and lift out.
Stabilizer Pin Holes
STABILIZER PINS
The speakers should be positioned before the stabilizer pins are installed.
Speakers positioned on a soft surface such as carpeting are able to rock back and forth slightly and will vibrate in reaction
to those forces the 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 information and reduces the clarity of the music.
To eliminate this effect, the THIEL CS3.6 can be used with the provided stabilizer pins. The stabilizer pins are pushed into
three pre-drilled holes in the base under each speaker. The pin point penetrates the carpet and allows the speaker to rest
firmly on the floor. The three pins provide a stable foundation which eliminates some obscuring of information and produces
a cleaner, more articulate sound. No pins are required when placing the speakers on hard or smooth surfaces.
There are some applications where the stabilizer pins will not bring an improvement in sound but may actually make it
worse. This situation occurs when the floor itself is not rigid and therefore vibrates when connected to the speakers via the
stabilizer pins. We encourage you to experiment to determine for yourself whether or not this is the case.
We recommend that you determine the position of your speakers before inserting the pointed stabilizer pins. To insert the
pins, tilt the speaker forward and push the two back pins fully into the 1" deep holes located in each back corner of the base.
Then rock the speaker backward and insert the front pin. Finally, press firmly on the top of the speaker with a slight rocking
motion until the pins penetrate the carpet completely. To check that the pins are firmly seated, lightly tap the back and side of
the speaker. There should be no movement and the speaker should feel solidly in place.
If the speaker is moved with the pins in place, care should be taken to lift the speaker straight upward until all the pins have
cleared the carpet. Also, tilting the speaker so its weight is resting on any single pin can damage the wood base.
Please be cautioned that the pointed pins can be dangerous if not used with care. They can cause small dents in hardwood
floors and it is possible to damage carpets if the speakers are moved incorrectly with the pins in place.

BREAK-IN
The CS3.6’s, like most speakers, require a period of playing before they perform optimally. The time depends on how loudly
the speakers are played; more time is required if played softly, less if played loudly. At least 50 hours at moderately loud
levels are required before the speaker is performing near optimum. You should notice even more improvement after 100
hours of playing.
ASSOCIATED EQUIPMENT
The CS3.6 is a very high quality sound reproducer and will benefit from use with the best associated equipment. Since it is
extremely accurate, it will reveal sources of distortion generated elsewhere in the system. For example, distortion resulting
from poor recordings or inferior electronics will be reproduced accurately. Also, the quality of the interconnect cables and
speaker cables will significantly effect the performance of the system.
POWER REQUIREMENTS
It is important to have enough power to play at the level you desire without distortion. If high sound levels are desired, the
CS3.6’s are designed to be used with amplifiers rated up to 400 watts per channel (into 4 ohms). If you play the speakers
more loudly than the volume the amplifier can cleanly produce, the amplifier will produce overload (clipping) distortion. The
sound will become compressed, strained, and in extreme cases, obviously distorted. This distortion is actually non-musical
additional energy and since it is concentrated in the high frequency region where the speaker is least able to handle it,
tweeters can be damaged in extreme cases.
Keep in mind that sound quality is usually much more important than sound quantity. There can be large differences in the
sonic performance of two amplifiers of equal power, and this is more important than large differences in power. Most
everyone will be happier with a 100 watt amplifier of high sonic quality than a 200 watt amplifier of mediocre sonic quality.
For this reason, we feel there is no substitute for listening in making your amplifier decision.
The question “how much power do I need?” does not have the simple answer most people expect because it is not
determined only by the loudspeaker’s efficiency, but also by the volume desired and the size of the room. If all three factors
are average, about 100 watts per channel is required. Each factor can raise or lower this amount by about three times.
1) Usually, people who “don’t like music loud” can decrease their power to 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.
2) A speaker with a low efficiency of 84dB/W-m will require twice the power of an average 87dB/W-m speaker and one
with a high rating of 90dB/W-m will require only half the power of an average speaker. Usually, high efficiency can be
obtained only by trading off sonic quality—there are very few speakers that provide a very high level of both. The CS3.6 is
of average efficiency (86 dB) and therefore requires a normal amount of power.
3) A small room will need less power for a given loudness level than a large room. A very small room of 1000 cu ft (11' x
11' with an 8' ceiling) will require about half the power of an average size room. A large room of 6000 cu ft (20' x 30' with a
10' ceiling) will require twice the average power. If the listening room is connected to another room by a large open area, the
required power will increase, but not by the amount of the combined room volume. If the room has a “dropped” ceiling with
light panels, the ceiling will be almost transparent acoustically and the space above the ceiling should be added. If the panels
are heavy they will act as a more normal ceiling.
With all this in mind, a person who doesn’t like to play music very loudly and has a small room can get quality sound with
as little as 50 watts whereas a person who sometimes likes to play loudly and has a large room may need 400 watts or more.
CABINET FINISH CARE
THIEL wood cabinets possess a high quality lacquer finish that is both beautiful and durable. However, any wood finish can
be damaged by excessive moisture, dryness, or direct sunlight. When cleaning your speakers, avoid using oils, waxes, or
polishes that contain silicone, such as Pledge or Johnson’s. We recommend using Endust. Non-wood laminate cabinets may
be cleaned with a glass-type cleaner and a soft cloth.

GRILLE
The CS3.6 grille is designed to not produce diffraction so there is no
sonic reason to remove it. If you do need to remove the grille, pull the
bottom of the grille frame away from the speaker an inch or so and
then lift the grille upward to remove it. When replacing the grille, first
push the top down onto the baffle and then push the bottom back.
The grilles can be cleaned of dust by using an upholstery attachment
of a vacuum cleaner. To prevent damage to the tweeter, take care not to
push the cloth in toward the top of the grille.

WE WANT YOU LISTENING FOR A LIFETIME
Used wisely, your new sound equipment will provide a lifetime of enjoyment. Since hearing damage from loud noise is often
undetectable until it is too late, THIEL and the Electronics Industries Association’s Consumer Electronics Group recommend
you avoid prolonged exposure to excessive noise. Depending on room size and amplifier power, some home audio systems
can reach sound pressure levels in excess of 95 decibels with peaks of over a 105 decibels. For your protection, the list below
identifies sound levels for various noises.
