    We will also offer some detailed suggestions on the setup of the X-1/GrandSLAMMs, but we strongly suggest that you have your local Wilson Audio dealer perform the final speaker “voicing” for you. They are specially trained in setting up Wilson loudspeakers and will ensure that you realize the full value of your purchase.

  • Page 14: Section 1.1-Room Reflections

    X-1/ G SLAMM O ’ RAND WNER ANUAL 1.1 R ECTION EFLECTIONS There are 3 commonly encountered room reflection problems: slap echoʼs, standing- waves, and comb filter effect. LAP ECHO Probably the most obnoxious form of reflection is called “slap echo.” With slap echo, primarily mid- range and high frequency sounds reflect off of two parallel hard surfaces.

  • Page 15: Standing Waves

  • Page 16: Comb Filter Effect

    X-1/ G SLAMM O ’ RAND WNER ANUAL In general, placement of the speaker in a corner will excite the maximal number of standing waves in a room, and is to be avoided for most direct radiator, full range loudspeaker systems. Some benefit is achieved by placing the stereo pair of loudspeakers slightly asymmetrically in the listening room.

    X-1/ G SLAMM O ’ RAND WNER ANUAL Occasionally, however, there is just enough resonance to give a little added warmth to the sound… an addi- tion some listeners prefer. Tube traps manufactured by the ASC Corporation are effective in reducing some of this low frequency room coloration.

  • Page 19: Speaker Placement Vs . Listening Position

    ISTENING OSITION The location of your listening position is as important as the careful setup of your X-1/ GrandSLAMM speakers in your room. The listening position should ideally be no more than 1.1 to 1.25 times the distance between the tweeters on each speaker. Therefore, in a long rectangu- lar room of 12ʼ...

  • Page 20: Speaker Orientation

    SLAMM should be “toed in.” In other words, the listener, when seated in the listening position, should just barely see the surface of the inner side of X-1/GrandSLAMM. Toeing in the speakers provides dramatic improvements in resolution of low level detail in the midrange, as well as dra- matic improvements in sound staging performance.

  • Page 21: Summary

    The speakers should be “toed in” toward the listener, preferably so that the listener at his seated position can barely see the surface of the inner side of the X-1/GrandSLAMM as he/she faces the speaker. It is recommended that a distance of 2-3 feet, and possibly more, be maintained between the X-1/Grand- SLAMM and the rear walls and a distance of at least 2 feet be maintained between the front panel of the X- 1/GrandSLAMM and reflective side walls.

  • Page 25 While the finish seems quite dry to the touch, final curing and complete hardening takes place over a period of several weeks. To protect the finish of the X-1/GrandSLAMM during final manufacture, shipment, and setup in your listening room, we have applied a removable layer of protective film over the finish.

  • Page 26: Break I N Period

    All audio equipment will sound its best after its components have been broken in for some period of use. Wilson Audio breaks in all woofers and mid-range drivers for a 12 hour period. All drivers are then tested, calibrated, and matched for their acoustical properties. In your listening room, expect 25 to 50% of break-in to be complete after two hours of playing music fairly loudly.

ONCLUSION All of these structural aspects combine to allow Wilson Audio to deliver a product that maintains the strictest structural tolerances, durability and reliability. This also means that you will have consistent, repeat- able performance, unaffected by the climatic conditions, anywhere in the world.

    NITIAL SSEMBLY In order to realize the capabilities of the X-1/Grand SLAMM we recommend that you have it installed by a trained Wilson Audio installer. Your dealer will have a person trained in the art of the X-1/Grand SLAMM installation. If you choose to do this installation yourself, here are some guide- lines to assist you.

Only tighten the bolt half way (see Figure 15). Repeat the same steps with the high frequency module (HFM), and again with the upper mid-range module (UMRM).

  • Page 43: Ounting The Pper Rossover

    The upper crossover sub-assemblies (U C/O S-A) are matched to each woofer. For example, if the serial number of the X-1 pair is 135 and 136, attach the U C/O S-A to the woofer with the same serial number. Install the U C/O S-A as follows: •...

  • Page 46: Connector Plate Jumper

    At all times, except during instrument pulse aligning the system, the jumper is to remain con- nected between jumper terminals. The X-1 system is now ready to be positioned in your room. NOTE: Until the X-1/Grand Slamm’s final position in your room is determined fully, do not tighten the hardware in the upper array.

  • Page 47: Materials Required

    (measured distances from the floor up to your ear), see Figure 20 below. For each distance/ear height combination there is a unique alignment geometry. To make correct in home set up of the X-1/Grand SLAMM possible without test equipment, Wilson Audio has measured the correct geometric time domain alignment for different distance/ear height combina- tions.

  • Page 48: Alignment Procedure

    Make sure that you are in your exact listening position. Be certain that your ear is aligned with your measured distance (as was stated of in the Wilson Audio setup procedure). While sitting, have someone measure your ear height from the floor. You should be relaxed in your chair, as you would be when listening to music.

  • Page 56: Leveling The X-1 Grand Slamm

    • Place a level on the front to back oriented axis. If it is level then your X-1 Grand SLAMMs are level. If the bubble is leaning toward the front of the room you will have to bring one of the front spikes down toward the floor.

  • Page 57: Section 4.6-Checking The Image Height

    Once the X-1/Grand SLAMMs are properly spiked, check for the proper image height. Small differ- ences in measurement of the listening distance can cause the image height to be too high. Check X-1 Grand SLAMMs for the correct height as follows: Sit in your listening position and listen to a piece of vocal performance that you know well.
