Operation; Removing The Grille And Loudspeaker - Niles HDFX Installation Manual

OPERATION

LISTENING AT HIGHER VOLUMES
Achieving a reasonable volume of sound in a large room requires more amplifi er power than it does
in a small room. It is possible to turn the volume up so high that the amplifi er 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 loudspeaker, turn the volume down immediate-
ly! Those harsh sounds are masking much more powerful ultra-high-frequency sound spikes, which
will quickly damage any fi ne loudspeaker. You are much less likely to damage a loudspeaker driven
by a large amplifi er because it will be very loud before any clipping distortion is produced.
CLEANING
Clean the Niles HDFX loudspeaker with a dampened soft cloth or paper towel. If the loudspeaker is
mounted high up on a wall or ceiling, use a broom to gently brush it off.

REMOVING THE GRILLE AND LOUDSPEAKER

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.
REMOVING THE LOUDSPEAKER
After removing the grille, use two small screwdrivers (or
needle-nose pliers) to release the snaps that hold the loud-
speaker (and baffl e) to the frame. Insert the screwdrivers into
the holes in the snaps and exert force straight down (towards
the woofer) until the snaps release, as shown in Figure 20.
Once the snaps release, the loudspeaker can be tilted away
from the frame to be removed.
NOTE: DO NOT ATTEMPT TO USE THE FRAME FOR LEVERAGE, AS
THIS MAY DAMAGE THE SURFACE OF THE FRAME.
