INSTALLATION CONSIDERATIONS
(CONTINUED)
As for placement height, place front left and right loudspeakers on either side of the
picture source so that their tweeters are not more than 24 inches above or below
the center-channel loudspeaker’s tweeter (see Figure 3 on page 7).
If the StageFront LCR loudspeaker is being installed in existing construction, please
use the included cardboard template to mark your installation location. Check for
proper clearance within studs or any other obstructions before cutting the speaker
opening. If you are unsure of the correct installation techniques, please consult your
authorized Niles Audio dealer.
NOTE: DO NOT PLACE ANY STAGEFRONT LCR OR FX LOUDSPEAKERS TOO CLOSE TO A DIRECT-VIEW
CRT TV MONITOR, AS IT MAY CAUSE PICTURE DISCOLORATION. IN GENERAL, TRY TO KEEP IT AT
LEAST 24 INCHES AWAY FROM THE TV. WITH LARGER CRT SCREEN SIZES, TEST THE PLACEMENT
DISTANCE FOR PICTURE DEGRADATION BEFORE INSTALLATION.
THE BOUNDARY EFFECT
Placing a loudspeaker in a corner can powerfully affect the way a listener
perceives bass response. Known as the boundary effect, placing loudspeakers
close to a wall/ceiling boundary or near a corner wall boundary will emphasize
certain bass frequencies, while canceling others. This effect can make the
loudspeaker sound excessively boomy and inaccurate to some listeners, while to
others it just seems like more bass sound.
As a good rule-of-thumb, if you like listening to your current pair of loudspeakers
with the bass turned up, you’ll enjoy corner placement. However, if you listen with
the tone controls at neutral, try keeping the loudspeakers at least 2 or 3 feet from
the boundaries of the room.
PLACING THE STAGEFRONT LCR AS THE CENTER-CHANNEL LOUDSPEAKER
The center-channel loudspeaker is the workhorse in a home theater system.
It handles all of the critical dialog and is vitally important in creating the illusion
of sounds emanating directly from the picture. Here are some tips for obtaining
optimum center-channel performance:
■ In a typical installation, place the loudspeaker horizontally, directly above or below
the television or projection screen. Try to ensure that the loudspeaker is not placed
too high relative to the left and right loudspeaker, as shown in Figure 3.
■ The IW2670LCR and IW2770LCR feature a midrange/tweeter pod that can be
rotated to accommodate horizontal installations. If you mount one of these models
horizontally, please remove the screws that hold this pod in place, rotate the pod
ninety degrees so that the tweeter is above the midrange and reinstall the screws to
reattach the pod to the loudspeaker as shown in Figure 4.
