C ongratulations on your purchase of the THIEL CS6 Coherent Source ® loudspeaker system. The CS6 is the result of a long and dedicated effort to provide the most accurate music reproduction possible. We have used only the highest quality components and taken great care in the CS6’s construction. Properly set up and used with good associated equipment, the CS6 will provide a great deal of musical enjoyment for many years. CONTENTS Design philosophy..................................
DESIGN PHILOSOPHY The CS6 is a precision instrument designed to translate, as accurately as possible, electronic information into musical sound. All our efforts have been directed toward achieving extremely faithful translation of all tonal, spatial and dynamic information supplied by the amplifier. The CS6 is not intended to mask or mitigate shortcomings of the recording or other components in the music playback system.
POSITIONING THE SPEAKERS Because of their unipolar radiation pattern and co-axial design, the CS6s will provide good results when placed in a variety of room locations. However, speaker placement will affect the accuracy of timbre, spatial performance, and bass performance. Here are some guidelines to help you achieve the best sound from your speakers. (The pointed metal stabilizer pins should not be installed until the final positioning has been determined.
Spacing Because of their very wide, even dispersion of energy, the CS6s can usually be placed farther apart than most other speakers. Optimum imaging is usually achieved when the speakers are almost as far apart as each speaker is from the listener, although this will depend on the width of the room—narrow rooms require more narrow placement.

Average listening room with long wall placement 18' 3' 3' 8' 5' 8' 5' 12' Some rooms, especially narrow ones, can benefit from placing the speakers along the long wall. Although space behind the speaker and behind the listener is reduced, this positioning increases the space between the speakers without side wall interference, and can improve overall performance.
CONNECTING THE SPEAKERS The CS6s’ input terminals are located on the bottom of the speaker near the back. Access is from the back with the speaker in its normal upright position. Make sure that both connections are tight. It is best to turn the amplifier off while connecting or disconnecting the speakers. For proper performance, both speakers in a stereo system must be wired in the same polarity. The speaker input terminals are color coded for this purpose.
BREAK-IN The CS6s, like most speakers, require a period of playing before they perform optimally. The time required 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.
6000 cu ft (20 ft x 30 ft with a 10 ft ceiling) will usually 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 lightweight panels, the ceiling will be almost transparent acoustically. In this case the space above the ceiling should be added. If the panels are heavy they will act more like a solid ceiling.
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 Manufacturers Association 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.
LIMITED WARRANTY THIEL warrants every THIEL model CS6 system against defects in materials and workmanship to the original owner for a period of ten years from the date of purchase. THIEL will, at no charge, replace any defective part and make any repairs necessary to ensure its proper performance when the defective unit is returned to us postpaid. This warranty does not cover damage due to accident or abuse and is void if the unit has been tampered with.
