D. VERTICAL ORIENTATION
The performance of your speakers is dependent on their
orientation. 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 section B above).
This means the speakers should always be vertically oriented.
The MP-150 is vertically oriented when its tweeters are vertically
stacked (not next to each other). When vertical, the controlled disper-
sion 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. See Figure 2.
5. USING THE MP-150 AS A SURROUND CHANNEL SPEAKER
While the MP-150 was designed primarily for use as a front channel speaker, its very high level of performance
makes it a superb surround channel speaker. It can be used in combination with any other M&K main speakers,
especially the S-150P, S-150, SW-150, and MP-150.
The MP-150 will perform equally well in both the side and back channels of 5.1, 6.1, and 7.1 channel systems and
is highly effective when used in multiple-speaker arrays.
The MP-150 should be installed using the attached wall-mounting system or M&K ST Wall Brackets. The speaker
should be oriented so that its front baffle is angled down, and it should be located at the listeners' ear level or above.
For most listeners, the preferred location for film soundtrack reproduction is at least two feet above the listeners'
heads. For 5.1 channel music reproduction, some listeners prefer that the surround speakers be mounted at the same
height as the front speakers. In most applications, the best overall result will be achieved with the speakers mounted
above the listeners' heads.
If you have any questions regarding the application of the MP-150 as a surround channel speaker, please contact
the M&K factory.
