    NSTALLATION IN We know you are eager to hear your Source speakers, so this section is provided to allow fast and easy set up. Once you have them operational, please take the time to read, in depth, the rest of the information in this manual.

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

    Break-In When you first begin to play your Source speakers, they will sound a bit bass shy. This is due to the high quality, long-life components used in our woofer. Our custom...

  • Page 8: Placement & Room Acoustics

    The Side Walls A good rule of thumb is to have the side walls as far away from the speaker sides as possible. However, MartinLogan’s unique controlled dispersion electrostatic transducer inher- ently minimizes side wall reflections—a position as little as two feet from the side walls often proves adequate.

  • Page 9: Final Placement

    On well recorded music, the instruments can extend beyond the edges of each speaker (left and right), yet a vocalist should appear directly in the middle. The size of the instruments should be neither too large nor too small, subject to the intent and results of each unique audio recording.

    Ideally, your room should not contribute to that information. However, every room does con- tribute to the sound to some degree. Fortunately MartinLogan had designed the Source to minimize these anomalies Terminology...

    It is best not to implement the spikes, however, until you are secure in the positioning, as the spikes can damage the floor if the speaker is moved. MartinLogan ETC spikes will fit any common 1/4” x 20 thread insert that may be found on your other audio equipment (racks, etc.)

  • Page 12: Dispersion Interactions

    By curving the radiating surface, we create the effect of a horizontal arc. This allows the engineers at MartinLogan to control the high frequency dispersion pat- tern of our transducers.

    Good subwoofers will provide a foundation for the rest of the system. Figure 13. Source speakers as front channels, Vignette speakers above the television and along the back wall as the center and surround (effects) channels, and Dynamo subwoofers in the front corners as the 0.1 (effects) channel.

  • Page 14: 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.

    Full Range Operation Another significant advantage of MartinLogan’s exclusive transducer technology reveals itself when you look at exam- ples of other loudspeaker products on the market today. The Source uses no crossover networks above 470 Hz because they are not needed. The Source consists of a single, seamless electrostatic membrane reproducing all frequencies above 470 Hz simultaneously.

    MartinLogan developed the production capability to bring it out of the laboratory and into the market place. You will find this proprietary MartinLogan technology used in all of our electrostatic products. It is one of the many reasons behind our reputation for high quality sound with practical usability.

    However, Lodge had no intention for his device to reproduce 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 18 The test instrument needed an extremely accurate speaker, but Janszen found that the cone speakers of the peri- od were too nonlinear in phase and amplitude response to meet his criteria. Janszen believed that electrostats were inher- ently more linear than cones, so he built a model using a thin plastic diaphragm treated with a conductive coating.

    Will my electric bill go ‘sky high’ by leaving my speakers plugged in all the time? No. A pair of MartinLogan’s will draw about 8 watts maximum (idle). There is circuitry to turn off the static charge when not in use; however, actual consumption will remain close to the same.
  • Page 20 How do MartinLogan speakers hold up over a long term in the humidity of tropical climates? We should tell you that MartinLogan indeed has a very substantial number of customers in tropical regions of the world. Our speakers have been serving them nicely for many years.

    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? • Try switching the left speaker with the right.
