Niles Audio HDLCR - Manual (Page 9)

NILES AUDIO CORPORATION – 1-800-BUY-HIFI
As for placement height, place front left and right speakers on either side of the picture source
so that their tweeters are not more than 24 inches above or below the center-channel speaker’s
tweeter (see
Figure 3 on page 8).
NOTE: DO NOT PLACE AN HDLCR SPEAKER TOO CLOSE TO A DIRECT-VIEW 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 speaker in a corner can powerfully affect the way a listener perceives bass response.
Known as the boundary effect, placing speakers 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 speaker 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 speakers with the bass turned
up, you’ll enjoy corner placement. However, if you listen with the tone controls at neutral, try keep-
ing the speakers at least 2 or 3 feet from the boundaries of the room.
