DESIGN PHILOSOPHY The CS3.7 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 CS3.7 is not intended to mask or mitigate shortcomings of the recording or other components in the music playback system. We believe this approach is the only way to provide the potential of ex

POSITIONING THE SPEAKERS Because of their unipolar radiation pattern, the CS3.7s 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 perfor- mance. 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 th

14' 2.5' 2.5' Spacing Because of their very wide, even dispersion of energy, the CS3.7s 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. If the speakers are too far apart for the room, there will tend to be a “hole” in the middle of the soundstage; if they are too close toget

18' 1' 1' 14' 18' 3' 3' 25' 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, 4' 10' 4' this positioning increases the space between the speakers without side wall interference, and can improve overall performance. Figure 4 shows the same average size room as Figure 3, but with long wall placement. The speakers should be at least a foot from the rear wall, but the 8-10 ' Listening D

CONNECTING THE SPEAKERS The CS3.7’s input terminals are located on the lower rear of the speaker cabinet. The CS3.7 uses 5-way binding posts that accept several types of wire connections. Regardless of the type of wire termination, make sure that all connections are tight. The input terminals are designed to be easily 1 tightened by hand or a ⁄2 inch nut driver can be used. It is essential for proper performance that both speakers in a stereo system be wired in the same polarity. The speaker’

BREAK-IN The CS3.7s, 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 CS3.7s are very high quality sound reproducers and will benefit from use wi

GRILLE The CS3.7 grille is attached magnetically to the front of the speaker. The grille is designed to not produce diffraction so there is no sonic reason to remove it. If you do need to remove the grille, carefully pull the grille frame away from the front of the speaker. When replacing the grille, line up the grille with the baffle’s inlay edges. OPTIONAL OUTRIGGER BASE The CS3.7s can be used with an optional Outrigger base (shown right). The Outriggers attache to the bottom of the speaker
