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.) All aspects of speaker placement are dependent on the particulars of the room.

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.

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.
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.
GRILLE The CS7.2 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.
