AC Power Connection 8 Controls and Connection Because your Summit speakers use an internal power supply to energize their electrostatic cells and to power the PoweredForce™ woofers, they must be connected to an AC power source. For this reason they are provided with the proper IEC standard power cor...

Single Wire Connection Controls and Connection 9 Please take note of the jumper clips installed under the binding posts. These clips attach the high and low fre-quency sections of the crossover together. Leaving these in place, connect the (+) wire from your amplifier to either red binding post and ...

By now your speakers should be placed approximately two to three feet from the front wall, the wall in front of the listening position, and about two feet from the side walls. Your sitting distance should be further than the distancebetween the speakers themselves. You are trying to attain the impre...

12 Placement Tilting the Speakers Backwards and Forwards— As the diagrams show in the Dispersion Interactions section of this manual (page 15), the vertical dispersion is directional above and below the stator panel itself. In some instances, if you are sitting close to the floor, slight forward til...

This is one of those areas that requires both a little back-ground to understand and some time and experimentation to obtain the best performance from your system. Your room is actually a component and an important part of your system. This component is a very large variable and can dramatically add...

Your Summit’s launch a 30 degree horizontal dispersion pattern. This horizontal dispersion field gives a choice of good seats for the performance while minimizing inter-actions with side walls (see figure 10). Make sure both speakers stand exactly at the same vertical angle, otherwise the image can ...

16 Home Theater It had long been the practice of stereo buffs to connect their television to a stereo system. The advantage was the use of the larger speakers and more powerful amplifier of the stereo system. Even though the sound was greatly improved, it was still mono and limited by the broadcast ...

Electrostatic Advantages 17 How can sound be reproduced by something that you are able to see through? Electrostatic energy makes this possible. Where the world of traditional loudspeaker technology deals with cones, domes, diaphragms and ribbons that are moved with magnetism, the world of electrost...

18 Electrostatic Advantages Another significant advantage of MartinLogan’s exclusivetransducer technology reveals itself when you look at exam-ples of other loudspeaker products on the market today. The Summit uses no crossover networks above 270 Hz because they are not needed. The Summit consists o...

XStat™ Transducer XStat™ transducers incorporate a myriad of technology anddesign innovations including CLS™, MicroPerf, Generation 2 Diaphragms, ClearSpars™, and Vacuum Bonding. CLS™ (Curvilinear Line Source) Since the beginning of audio, achieving smooth dispersion has been a problem for all desig...

20 Electrostatic History In the late 1800’s, any loudspeaker was considered exotic. Today, most of us take the wonders of sound reproduction for granted. It was 1880 before Thomas Edison had invented the first phonograph. This was a horn-loaded diaphragm that was excited by a playback stylus. In 189...

Electrostatic History 21 In 1947, Arthur Janszen, a young Naval engineer, took part in a research project for the Navy. The Navy was interested in developing a better instrument for testing microphone arrays. The test instrument needed an extremely accurate speaker, but Janszen found that the cone s...

22 Frequently Asked Questions How do I clean my speakers? Use a dust free cloth or a soft brush to remove the dust from your speakers. We also recommend a specialty cloth (available at the Xtatic shop at www.martinlogan.com) that cleans your speakers better than anything else we have tried. For the ...
