AC Power Connection 8 Controls and Connection Your Summit X speakers use an internal power sup- ply to energize their electrostatic cells and the amplified PoweredForce™ woofer system, and must be connected to an AC power source. For this reason they are provided with the proper IEC standard power c...

10 Controls and Connection 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 at least two feet from the side walls. Your sitting distance should be further than the dis- tance between the speakers themselves. Y...

Placement 11 Toe-in— Now you can begin to experiment. First begin by toeing your speakers in towards the listening area and then facing them straight into the room. You will notice the tonal balance and imaging changing. You will notice that as the speakers are toed-in, the system becomes slightly b...

12 Placement good pinpoint focusing. Your ideal listening position and speaker position will be determined by: • Tightness and extension of bass response • Width of the stage • Pinpoint focusing of imaging Once you have determined the best of all three of these considerations, you will have your bes...

Room Acoustics 13 the frequencies generated by your system. Much like an instrument, they will vibrate and “carry on” in syncopation with the music, and contribute in a negative way to the music. Ringing, boominess, and even brightness can occur simply because they are “singing along” with your musi...

Your Summit X’s launch a 30 degree horizontal disper- sion pattern. This horizontal dispersion field gives a choice of good seats for the performance while minimiz- ing interactions with side walls (see figure 9). Make sure both speakers stand exactly at the same vertical angle, otherwise the image ...

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 exclusive transducer technology reveals itself when you look at exam- ples of other loudspeaker products on the market today. The Summit X uses no crossover networks above 270 Hz because they are not needed. The Summit X cons...

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...

24 Troubleshooting No Output • Check that all your system components are turned on. • Check your speaker wires and connections. • Check all interconnecting cables. • Try hooking up a different set of speakers. The lack of output could point to a problem with other equipment in your system (amp, pre-...
