  • Page 5: Installation .In .Brief

    Attach your speaker cables to the signal input section on the rear panel. Be consistent when connecting speaker leads to the terminals on the back of the CLX. Take great care to assign the same color cable to the (+) terminal on both the left and right channels.

    The materials in your new CLX speakers are of the high- est quality and will provide years of enduring enjoyment with deepening respect. The cabinetry is constructed from the highest quality materials for acoustical integrity.

    Proper break in will improve bass extension. The high quality components used in our electrostatic panels may cause your CLX speakers to sound a bit bass shy when they are first used. CLX requires approximately 100 hours of break-in at 90 dB (moderate listening levels) before any critical listening.
  • Page 8: Setup .And .Placement

    Left/Right Speaker Placement Place your CLX speakers so the curvilinear electrostatic transducer is orientated inside, towards the listening posi- tion (figure 3). Listening Position By now your speakers should be placed so the electrostatic panels are approximately four feet from the front wall (the wall in front of the listening position) and about two feet from the side walls.
  • Page 9: Final Placement

    Imaging—In their final location your CLX speakers may have a stage width somewhat wider than the speakers themselves. On well-recorded music, the instruments can extend beyond the outer edges of each speaker (left and right), yet a vocalist should appear directly in the middle.

    Ideally, your room should not contribute to that information. However, every room does influence the sound to some degree. Fortunately MartinLogan has designed the CLX to minimize these anomalies. Let’s talk about a few important terms before we begin.

    The low frequencies can either be enhanced or nulled by the position from the front wall. Your CLX’s have been Room Acoustics designed to be placed four or more feet from the front wall (the wall in front of the listening position) to obtain the best results;...
  • Page 13: Dispersion Interactions

    As you can see from the illustrations, your CLX speakers project a controlled dispersion pattern (see figure 12). Each CLX is a 57 inch line source beginning 9 inches above the base. This vertical dispersion profile minimizes interac- tions with the floor and the ceiling.

    Good subwoofers will provide a founda- tion for the rest of the system. Figure .13 . CLX speakers as front channels, the Stage as the center and surround channels, and Descent i subwoofers as 0.1 (effects) channel.
  • Page 15: Electrostatic .Advantages

    Since the diaphragm of an electrostatic speaker is uniform- ly driven over its entire area, it can be extremely light and flexible. This allows it to be very responsive to transients, thus perfectly tracing the music signal.
  • Page 16: Full Range Electrostatic Operation

    The CLX uses no crossover networks above 360 Hz because they are not needed. The CLX has a single elec- trostatic transducer reproducing all frequencies above 360 Hz simultaneously. How is this possible? First we must understand that music is not composed of separate high, mid and low frequency pieces.

    It is significant to note that the XStat™ transducer in the radical new CLX loudspeaker supports the bandwidth and dynamics associated with traditional electrostatic panels nearly twice its size.

    These materials are bound by a revolutionary co-polymer resin system that is 100% water based and VOC free. CLX is the obvious first applica- tion for this remarkable new audiophile grade material and yet another giant step forward in Martin Logan’s continu- ing commitment to produce irresistible high value products from environmentally intelligent materials.

    However, Lodge had no intention for his device to repro- duce music because in 1898 there was no way to amplify an electrical signal! As a result, his speaker had nothing to offer over the acoustical gramophones of the period. It was not until 1906 that Dr.
  • Page 20 The test instrument needed an extremely accurate speaker, but Janszen found that the cone speakers of the period were too nonlinear in phase and amplitude response to meet his criteria. Janszen believed that electrostats were inherently more linear than cones, so he built a model using a thin plastic diaphragm treated with a conductive coating.

    Do they have the same amount of toe- in? Try moving the speakers away from the back and sidewalls. • Check the polarity of the speaker wires. Are they con- nected properly? • Are your speakers set up in an L-shaped room? If so, you may experience off-center imaging.

    It is a combination of resistance and reactance and is measured in ohms. Remember that a speaker’s imped- ance changes with frequency, it is not a constant value.

  • Page 28 WARNING! Do not use your CLX loudspeakers outside of the country of original sale—voltage requirements vary by country. Improper voltage can cause damage that will be potentially expensive to repair. The CLX is shipped to authorized MartinLogan distributors with the correct power supply for use in the country of intended sale. A list of authorized distributors can be accessed at www.martinlogan.com or by emailing info@martinlogan.com.
