Installation in Brief 5 We know you are eager to hear your Summit X 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.
6 Introduction Co ng ra t u l at io ns ! Yo u ha ve i nv es te d in on e of t he w or ld ’s premier loudspeaker systems. The MartinLogan Summit X™ represents an advanced combination of sonic technologi es establi shing an unprec- edented direction for audiophile design.
Controls and Connections 7 C ontrols and C onneCtIons 25Hz Level Knobs The 25Hz Level knob sig- nificantly adjusts the level between 20 and 30Hz by ±10dB. This is an area where peaks and dips of different amplitudes often manifest in real environments.
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 po wer sour ce. For this reason t hey are provided with the proper IEC standard power cords.
Controls and Connection 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.
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.
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 brighter than when toe d-out.
12 Placement good pinpoint focusing. Your ideal listening position and speaker position will be determined by: • Tightnessandextensionofbassresponse • Widthofthestage.
Room Acoustics 13 the frequencies generated by your system. Much like an instrum ent, they will vibrat e an d “ca rry on” in sy ncopat ion with the music, and contribute in a negative way to the music. Rin ging, boomi ness, and even bri ghtness c an occu r simply because they are “singing along” with your music.
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.
Your Summit X’s launch a 30 degree horizontal disper- sion patte rn. This horizontal dispersion field gives a choice of good seats for the performance while minimiz- ing interactions with side walls (see figure 9).

22 Frequently Asked Questions How do I clean my speakers? Use a dust free cloth or a soft brus h to remov e 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.
Frequently Asked Questions 23 Will excessive smoke or dust cause any problems with my electrostatic speakers? Exposure to excessive contaminants such as smoke or dust may potentially affect the performance of the electrostatic membrane, and may cause discoloration of the diaphragm membrane.
