3.0 Speaker Placement
Now is a good time to finalize your plans for
speaker placement. This section outlines the
important issues to consider in configuring your
system for optimum performance.
The M5 and M6 monitors are designed to per-
form almost identically whether placed horizon-
tally or vertically. Below are some fundamental
guidelines on Monitor orientation:
1) You do not need to “toe-in” the monitors
toward the listening area; position them facing
straight ahead into the room, perpendicular to
the wall in behind the speaker.
2) When oriented vertically, the tweeters
should be placed inward as shown below.
3) When using the M5 or M6 monitor for a
center channel, it should be placed horizontally.
4) When Evolution monitors are placed hor-
izontally in a cabinet, the tweeter orientation (top
or bottom) depends on the placement height. If
the monitor is placed above the listener’s ear,
the tweeter should be below the midrange driver
as shown in the photo. If the monitor is placed
below the listener’s ear, the tweeter should
above the midrange driver.
Once you have determined how you will orient
your monitors, examine the terminal plate on the
back of your Evolution Monitor. You will find a
Boundary Switch on the plate that is used to
adjust the speaker’s response based on its
placement. If you intend to place the monitor in
a cabinet, on a shelf, on top of a television set or
against a wall, move the boundary switch to the
“1” position. If the monitor is two feet or more
from any surface described above, the switch
should be in the “0” position. If the Monitor is
used as part of a T5 or T6 Tower system, the
Boundary Switch should generally be in the “0”
position. If the Tower system is placed very
close to a corner, set the switch to the “1” posi-
tion.
Note: The terminal plate comes from the facto-
ry oriented for horizontal placement. This allows
speaker wire to hang down neatly from the
speaker. The terminal plate should be rotated
for vertical use. Instructions for rotating the cup
can be found in section 4.2.
An explanation of the technology behind the
guidelines described above can be found in sec-
tion 11 of this manual.
