    We have used only the highest quality components and taken great care in the CS3.7’s construction. Properly set up and used with good associated equipment, the CS3.7 will provide a great deal of musical enjoyment for many years.
  • Page 3: Design Philosophy

    The CS3.7 is not intended to mask or mitigate shortcomings of the recording or other components in the music playback system.
  • Page 4: Positioning The Speakers

    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 the particulars of the room.
  • Page 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.
  • Page 6 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.
  • Page 7: Connecting The Speakers

    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.

    2) A speaker with a low efficiency of 84dB/2.8 V-1-m will require twice the power of an average 87dB/2.8 V-1-m speaker and one with a high rating of 90dB/2.8 V-1-m will require only half the power of an average speaker. The CS3.7 is of high efficiency (90dB) and therefore can work well with smaller amounts of power from a quality amplifier.
  • Page 9: Grille

    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.
