For example, with a 25" direct-view television, you would want the
speakers closer together than you would with a 100" projector. One
recommendation is to separate the speakers by 1.5 times the diago-
nal screen size; another is to place the left and right speakers to cre-
ate a 45 degree angle with the main listening position.
There is a great deal of latitude in this area, as it is one of personal
preference (especially if you will listen to music without video).
It is also preferred that the speakers be equidistant from the listen-
ing position. Equidistant usually means that when the center speaker
is on top of the television, the left and right speakers will sit in front of
the set (they will be farther from the wall behind the TV than the center
speaker). Ideally, the speakers should be at the same height as the
screen, but it is much more important that all three speakers be as
close to each other's height as possible. If the center is much higher
or lower than the other speakers, the effect can be distracting. An-
gling, or toeing-in the speakers, to aim at the listening position often
improves imaging.
When using a Center channel speaker, you have extra flexibility in
placing the left and right speakers, as the Center channel speaker will
tie most dialog and effects directly to the screen.
The Surround channel speakers can be placed in a wide variety of
locations in the room to give good performance. In general, the sur-
round speakers should be either adjacent to or behind the main listen-
ing position, and located higher than the listener's heads. They can
be mounted on either the side walls or on the back wall, flush to the
wall, on shelves, on brackets, etc.
The goal is to achieve an enveloping sound. The surround channels
should seem to come from all around you, rather than seeming to
come from behind you only or directly from a speaker.
This section discusses non-THX surround speakers. THX system
requirements call for dipolar surround speakers mounted to the sides
of the listening position above the listeners' heads. See M&K's THX
surround speaker instruction manual and the THX Installation Guide
for detailed instructions.
M&K's ST series of stands can be used to mount surround speak-
ers at virtually any height, including well above listeners' heads, sim-
ply by using a custom length of pipe to set the height.
For non-THX surrounds, try starting with speakers on the side walls
of the room, two to three feet above the listeners' heads, directly adja-
cent to the listening position or behind it. You can aim the speakers to
fire towards each other (across the listening area), or you can aim
them to fire towards the back wall at an angle. When possible, the
surround speakers should not be in front of the main listening position.
