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 Figure 20. Pivoting the HDLCR’s tweeter. installed, the grille will be absolutely flush in

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.
