Page 6: Introduction
Congratulations! You have invested in one of the world’s premier loudspeaker systems . The MartinLogan Summit X™ represents an advanced combination of sonic technologies establishing an unprec- edented direction for audiophile design. The result of years of research, the new Summit X™ hybrid electro- static loudspeaker features PoweredForce™... -
Page 7: Controls And Connections
Signal Input These binding posts provide a place to connect the Summit X to your amplifier. AC Power Connection Your MartinLogan Summit X speakers use an internal power supply to energize their electrostatic cells and PoweredForce™ woofers, and must be connected to an AC power source. -

On the rear of the Summit X are two knobs that control the 25Hz and 50Hz frequency responses by ±10db. MartinLogan engineers have found this frequency area (20–75Hz) to be problematic. Low frequencies tend to react to a room environment by creating nodes (boomy and unnatural bass) or nulls (weak bass). - Page 9 drum or a pipe organ). When adjusting the 25Hz and 50Hz levels we recommend doing so with two or three people—one located at the listening position and one or two people at the controls. 1 Start with the 25Hz and 50Hz level knobs set to 0dB. The person at the listening position needs to become familiar with the sound at this setting.

The Side Walls A good rule of thumb is to have the side walls as far away from the speakers as possible. However, MartinLogan’s unique controlled dispersion electrostatic transducer inherently minimizes side wall reflections—a position as little as two feet from the side walls often proves ade- quate. -
Page 11: Experimentation
Experimentation 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 brighter than when toed-out. -

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

(See ‘Solid Footing’ for spike information and installation instructions). Dipolar Speakers and Your Room MartinLogan electrostatic loudspeakers are known as dipolar radiators. This means that they produce sound from both their fronts and their backs. Consequently, musical information is reflected by the wall behind them and may arrive, either in or out of step, with the informa- tion produced by the front of the speaker. - Page 14 The Summi X’s feet can be configured to adjust the rake of the speaker from –1° to 11° allowing precise control of the speaker’s vertical dispersion (figure 4). Spike Installation Instructions: 1 Carefully lay your speaker on its side. 2 Remove existing feet. Thread the spikes into the holes and screw them in all of the way.

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. Dispersion Interactions... -

Home theater is a complex purchase and we recommend that you consult your local MartinLogan dealer, as they are well versed in this subject. Each piece of a surround system can be purchased sepa- rately. -
Page 17: Electrostatic Advantages
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 electrostatic loudspeakers deals with charged electrons attracting and repelling each other. -
Page 18: Full Range Operation
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 Summit X uses no crossover networks above 270 Hz because they are not needed. The Summit X consists of a single, seamless electrostatic membrane reproducing all frequencies above 270 Hz simultaneously. -

MartinLogan developed the production capa- bility to bring it out of the laboratory and into the market place. You will find this proprietary MartinLogan technol- ogy used in all of our electrostatic products. It is one of the many reasons behind our reputation for high quality sound with practical usability. -
Page 20: Electrostatic Loudspeaker History
leCtrostatIC 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 1898, Sir Oliver Lodge invented a cone loudspeaker, which he referred to as a “bellowing telephone”, that was very similar to the conventional cone loudspeaker drivers that we know today. - Page 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 speakers of the period were too nonlinear in phase and amplitude response to meet his criteria.

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 wood surfaces it is accept- able to slightly dampen the cloth. - Page 23 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.

rouBlesHootIng 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-amp, processor, etc.) Weak or no Output from Electrostatic Panel, Loss of Highs • Check the power cord. Is it properly connected to the speaker and to the wall? • Is the power cord connected to a switched outlet? • Dirt and dust may need to be vacuumed off. Please see the FAQ regarding vacuuming. -
