D. VERTICAL ORIENTATION
The performance of your speakers is dependent on their orientation. THX speakers are designed for
controlled vertical dispersion and wide horizontal dispersion. By controlling the vertical dispersion, we limit the
amount of sound that would otherwise be reflected with a time delay from the floor and ceiling (for the reasons
discussed in B. above).
This means the speakers should always be vertically oriented. The S-150 is vertically oriented when its
tweeters are vertically stacked (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 and S-150 must be oriented vertically (tweeters in a vertical line) to meet THX
requirements.
6. SPEAKER PLACEMENT IN A HOME THX AUDIO SYSTEM
If your M&K speakers are being used in a Home THX Audio system, placement is very important.
You should take at least the same amount of time and care in setting up your M&K Home THX 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 and S-150 are less influenced by the room environment than most other speakers,
the time you spend in carefully installing them will significantly enhance your enjoyment of them later.
The Left, Center and Right speakers should ideally all be at the same height as the television screen.
Because the Center channel speaker cannot cover the screen, in will have to be placed above or below the screen.
Try to set up all three speakers at the same height. If this is not practical, set them up so that they are no further
apart vertically than the speakers' two foot height. In other words, the bottom of the speaker the farthest from
the floor should be no higher than the top of the speaker closest to the floor.
Remember that the speakers need to be aimed at the listening position when they are not placed with the
