Speaker Placement - BLUE SKY BMC MK III User Manual

Satellite Speaker Placement - MUSIC
The recommended monitoring angle for proper stereo imaging with music
is 60 degrees between the left and right speakers. The center channel
speaker should be located on axis with the reference monitoring position
and both the left and right surround channel speakers should be at an angle
of 110 degrees from the center line. In most applications, surrounds used
for music are placed at the same height as the front speakers for a direct
sound field. See Figure 1
Satellite Speaker Placement - FILM / POST PRODUCTION
Although the above recommendations should work equally well for both film
and music production, there may be situations where a more "film" optimized
setup is desirable. To correctly relate audio to picture, the recommended
angle between left and right speakers is 45 degrees. This narrower
monitoring angle should still yield a very satisfactory stereo image. As with
the "music" setup, the center channel speaker, should still be located on
axis with the reference monitoring position. Unlike music surrounds, which
tend to be direct in nature, film surrounds are usually positioned for a more
diffused sound field, to simulate the effect of an array of surround speakers
used in a theater. For a single pair of surrounds, this can be accomplished by
placing them two feet above seated ear height, to the side of the monitoring
position and slightly behind the mix position. For larger rooms, it may also
be desirable to use multiple surround speakers as an "array".
Satellite Speaker Monitoring Height Recommendations
It is recommended that all of the satellite speakers be placed at or about
seated ear height, as shown in Figure 2. If it is not possible to place the
speakers at or about seated ear height, please aim the speakers at the
monitoring position.
Subwoofer Speaker Placement
Although you have great flexibility in positioning a subwoofer, a good
starting point is centered between the left and right satellite speakers. This
could be under the console, behind the console, etc. Placing the subwoofer
closer to a corner or wall will increase acoustic efficiency and may yield
better acoustic response in many situations. However, because of the
many variables that relate to "in-room" subwoofer performance, we highly
recommend experimenting with subwoofer placement. Visit the Blue Sky
website for more detailed and specific recommendations.
Speaker placement recommendations, with regard to these types of
installations, vary greatly on the end users' goals and surround philosophy.
For more specific information regarding your particular installation, please
