5. Speaker Placement
When the S-150P is used as a front loudspeaker it should be located with the center
tweeter at seated ear height. If this is not possible the S-150P must be aimed at seated ear
height at the center of the primary seating/monitoring location so as to cover the listening area
uniformly with high frequency energy.
The S-150P is provided in LEFT and RIGHT versions. They are identified by the
location of the tweeters when the speaker is viewed from the front.The LEFT speaker has
the tweeters located on the left side of the front baffle and the RIGHT speaker has the
tweeters on the right side.
Either version can be used as the center channel.
6. Narrow / Wide Mode
After final aiming of the loudspeaker system has been completed, smooth front to back
coverage should be confirmed throughout the monitoring area. In the narrow mode (THX
recommended), the S-150P will minimize floor and ceiling reflections, providing smoother
horizontal on and off axis frequency response. When multiple rows of seats need to be covered,
or the monitoring area is larger than the Narrow Mode will cover, it is recommended that the
S-150P be used in its Wide Mode. This mode widens the vertical coverage angle, but also makes
the speaker more susceptible to room boundary interference. Determining which mode best
suites your monitoring condition might require some experimentation.
7. Optimizing Speaker Location
The sound quality produced by your speakers can be significantly enhanced by careful
attention to their placement. While we understand that you may not redesign your room to
accommodate your speakers, coming as close as possible to the ideal placement will give you
much better sound.
Four factors are important in getting the best sound. They are:
A. Height (or angle).
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)
Your M&K speakers will always deliver sound superior to conventional speakers, regardless
of where you locate them. However, because they are designed for very fast and accurate
transient response, they achieve even better sound quality, and the flattest frequency response
when properly oriented relative to your ear. Ideally, the tweeters should be at the same height
from the floor as your ears, when you are sitting in your main listening position. If you have the
speakers mounted above or below this height, they sound their best when you angle the
speakers so that the tweeters are aimed at your ears when you are in the main listening
position.
