Of course, there are some wires that appear completely identical. So be careful, or you might make
a connection mistake. If you do, one loudspeaker will be playing “out-of-phase” with the other
loudspeaker. A pair of out-of-phase loudspeakers works against each other, and the sound of the
two 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 loudspeakers.
2. Play some music with the amplifier or receiver 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 loudspeakers are working together or “in-phase.”
INSTALLING THE GRILLE
If desired, at each loudspeaker, carefully fit the grille to its cabinet. Starting with one corner, gently
press the grille frame around the loudspeaker’s edge, pushing it in at each of the four recessed
holes. When properly installed, the grille will be absolutely flush in appearance with the cabinet.
