THIEL Model CS7.
C ongratulations on your purchase of the THIEL CS7.2 Coherent Source ® loudspeaker system. The CS7.2 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 CS7.2’s construction. Properly set up and used with good associated equipment, the CS7.2 will provide a great deal of musical enjoyment for many years. CONTENTS Design philosophy..................................
DESIGN PHILOSOPHY The CS7.2 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 CS7.2 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 CS7.2s 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 CS7.2s 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 CS7.2s’ 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, all speakers in the system must be wired in the same polarity. The speaker input terminals are color coded for this purpose.
BREAK-IN The CS7.2s, 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. ASSOCIATED EQUIPMENT The CS7.
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.
