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 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 fine loudspeaker. You are much less likely to damage a loudspeaker driven by a large amplifier 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 baffle) 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.
