Niles Audio DS00420ACN Boundary Effect, Placing AN Hdlcrbx AS the CENTER-CHANNEL Loudspeaker

As for placement height, place front left and right loudspeakers vertically 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 2 on page 6). For best response, orient the loudspeakers so the tweeters face out.

NOTE: DO NOT PLACE AN HDLCRBX LOUDSPEAKER TOO CLOSE TO A DIRECT-VIEW TV MONITOR, AS IT MAY CAUSE PICTURE DISCOLORATION. 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 re- sponse. 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 AN HDLCRBX 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 HDLCRbx horizontally, directly above the television or projection screen. Try to insure that the loudspeaker is not placed too high relative to the left and right loudspeakers, as shown in Figure 2 (on the next page).
