ADJUSTING THE TWEETER
(CONTINUED)
3. Pivot the tweeter on each speaker equally
by depressing the housing at the arrows
until the desired angle is achieved, as
shown in Figure 20.
INSTALLING THE GRILLE
At each speaker, carefully fit the grille into its recess
so that it is barely in place. Starting with one corner,
gently press the grille around the speaker, pushing
it in a little bit each time. Be gentle – the aluminum
grille can be easily bent out of shape. When properly
installed, the grille will be absolutely flush in
appearance with the surrounding frame.
OPERATION
LISTENING AT HIGHER VOLUMES
Achieving a reasonable volume of sound in a large room requires more amplifier power than it does
in a small room. It is possible to turn the volume up so high that the amplifier runs out of power.
This creates “clipping” distortion, which will make treble sound very harsh and unmusical.
When you hear harsh-sounding treble from any good speaker, turn the volume down immediately!
Those harsh sounds are masking much more powerful ultra-high-frequency sound spikes, which
will quickly damage any fine loudspeaker. You are much less likely to damage a speaker driven by a
large amplifier because it will be very loud before any clipping distortion is produced.
CLEANING
Clean the Niles HDLCR loudspeaker with a dampened soft cloth or paper towel. If the speaker is
mounted high up on a wall or ceiling, use a broom to gently brush it off.
REMOVING THE GRILLE AND SPEAKER
REMOVING THE GRILLE
If you need to remove an installed grille, use a bent paper clip or the tip of a corkscrew to gently
pull it away from the frame.
