1. Four factors are important in getting the best sound They are A Height or angle proper orientation of tweeters relative to listeners ears B Location away from room walls or reflecting surfaces C Separation between left and right speakers D Vertical orientation of the speaker cabinets A HEIGHT OR ANGLE The S 5000 S 250 and S 150 have a controlled vertical radiation pattern that makes the speaker s location critical It is very important to aim the tweeters at the main listening position in order to achieve their very best sound quality and their flattest frequency response Ideally your speakers tweeters should be at the same height from the floor as your ears when you are sitting in your main listening position Specifically this means the distance from the floor to the space between the two tweeters S 5000 or to the center tweeter S 150 amp S 250 If you have the speakers mounted above or below this height you must tilt the speakers so that the tweeters are aimed at your ears when you are in the main listening position If you have the special Angled Center S 150AC its front baffle has a built in tilt that aims the sound either up or down depending on orientation This speaker is ideal for use as the center channel speaker sitting on top of a rear projection television set You can start by aligning the speakers visually Sit in your main listening position and look at the cabinets tops and bottoms2.

3. When their perspective is about the same relative to where you are sitting about the same angle you are at least very close to the proper alignment The best way to determine the proper angle is to have a helper move the speakers while you sit and listen You should be able to hear the difference when the speakers are in the best location by listening for the brightest high frequencies and for the best focus of sound where you hear the sharpest sonic imaging of voices and instruments To aim the speakers more precisely we recommend using a laser alignment tool One can be purchased from M amp K simply visit our web site or call M amp K directly B LOCATION AWAY FROM REFLECTING SURFACES Your speakers should generally be located away from walls furniture or any other reflecting surfaces Any object located close to the speaker will reflect the sound radiated from the speaker to your ear with a slight time delay compared to the direct sound reaching your ear This time delay will blur the sonic imaging and interfere with transient performance The delay is very slight so instead of hearing an echo you hear a blurred sound with less clarity that is not as sharp and distinct as it should be This time delay also affects frequency response and sonic imaging Bear in mind however that while many satellite speakers do not perform well when placed on the floor the S 5000 is designed to deliver good performance whether sitting on the floor or
4. not next to each other When vertical the controlled dispersion is in the correct plane If they are oriented horizontally on their sides listeners right or left of a direct line from the center of the speaker will hear a compromised sound quality an irregular frequency response as well as some other problems While this may be acceptable for background listening we strongly recommend that you do not place them on their sides for any other listening The S 5000 S 250 and S 150 must be oriented vertically tweeters in a vertical line See Figure 3 A S 5000 and Figure 3 B S 150 amp S 250 MAIN SATELLITE SPEAKER FIGURE 3 A FIGURE 3 B CORRECT Ss ORIENTATION ols OF Z 90 CORRECT 3 ORIENTATION PX S 5000 ed INCORRECT ORIENTATION gt gt INCORRECT ORIENTATION S 5000 K 6 SPEAKER PLACEMENT IN A HOME AUDIO SYSTEM Placement is very important You should take at least the same amount of time and care in setting up your M amp K speakers as you would with the most exotic high end stereo system Some listeners make the mistake of taking too casual an approach to the installation of speakers in a home theatre system In fact in many ways the setup of speakers in a home theatre is more critical than for stereo Even though the S 5000 S 250 and S 150 are less influenced by the room environment than most other speakers the

6. best balance between stereo image localization and maximum impact and output in the mid bass you have the ideal location 9 MAIN SATELLITE SPEAKER 10 SPEAKER DAMAGE amp HOW AVOID IT An important factor to consider with any loudspeaker system is the potential for speaker damage Even though your speakers have extremely high power handling ability they still can be damaged by relatively low powered amplifiers While very few M amp K Satellites are actually returned for service the vast majority of those returned are not for manufacturing defects Instead they are returned because they have been overdriven almost always because the amplifier or receiver used was driven into clipping distortion This damage is considered abuse and is not necessarily covered under warranty This clipping distortion occurs when the demands of the music are greater than the amplifier s available power It can occur at 20 watts with a small amplifier or at 400 watts with a large amplifier Regardless when this happens the amplifier s output waveform which usually looks like a smooth arc is clipped off exhibiting a flat top instead of the arc This flat top contains multiples of the original amplified frequencies sometimes at higher levels than the original signal itself For tweeters this can be very damaging as this distortion is well above the audible range where you will be unable to hear it and where the tweeter is more vulnerable to
7. damage When an amplifier clips its sound becomes harsh and grating and a break up is often audible in the bass frequencies It will become uncomfortable to listen to compared to a slightly lower volume level When you are listening at high volume levels be aware of the onset of clipping distortion and turn the volume down slightly if the sound takes on the character described above When tone controls or equalizers are used to boost frequencies the problem occurs much more rapidly Even a small boost of low or high frequencies can easily double the power requirement and lead to amplifier clipping at moderate levels Therefore you should use your tone controls judiciously avoiding extreme boosts of the bass and treble controls especially when you are listening at high volume levels The best way to avoid speaker damage is to use common sense Use moderate boosts of tone controls or equalizers at the very most Listen carefully for any harshness and break up especially at high volume levels and turn down the volume when needed If you cannot get enough volume you may need to consider higher powered amplifier If you have any questions about this please contact M amp K or your local M amp K dealer FIGURE 8 11 M amp K WALL MOUNT BRACKET AND STAND OPTIONS We recommend using M amp k s ST series of floor mount stands for your Ig 5 5000 5 250 S 150 speaker See Figure 8 These stand
