Verifying Phase
When proper polarity is not maintained, the speakers play at the opposite ‘time’ from
each other, or out of phase. The result is audio with lack of bass and vocals that sound
thin or distant. If during or after calibrating your amplifier you suspect the sound is not
right and you cannot see any markings on the wire to verify polarity is correct, try this
simple test:
1. Sit in the normal listening position for the system.
2. Play some music and listen for the following characteristics.
A. Does the bass sound full and even with the other audio?
B. Do the vocals sound centered and even in volume?
If either of the answers are YES, follow steps 3 and 4 with the other
loudspeakers in the system.
3. Turn off your receiver and reverse the connections for one of the speakers.
4. Repeat your test at the same volume level. When the sound has the loudest and
best sounding bass, and vocals are centered and clear, your connections are correct
and in-phase.
Cleaning
• Use a soft cloth or paper towel with mild detergent to clean the speaker.
