playing together will be lacking in bass and sound “phasey.” If you suspect the sound is not right,
and you cannot see any markings on the wire, try this simple test:
1.
Stand halfway between the speakers.
2.
Play some music with the amplifier or radio set to Mono.
3.
Listen to the richness of the bass and the loudness of the sound.
4.
Turn off the amplifier and reverse the connections on one amplifier channel only.
5.
Repeat the listening test with the same volume control setting. When the sound has a
richer bass and is slightly louder, the speakers are working together or “in-phase.”
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 CM6HDfx 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.
