Do we know the weighting our brains place on phase differences?
Quite a bit. Try this experiment. Take a stereo, wire the two speakerscorrectly (in phase), separate them by about 10 feet, and
then play a MONO source through both speakers (a voice works really well).Stand midway between the speakers and back
about 10 feet. You will easily localize the sound as coming from betweenthe two speakers. Now reverse the wires on ONE of
the speakers. The sound you now hear will be diffuse and withoutparticular direction. [This was the phasing test I had on an old
setup record. A voice was recorded on both channels first in phase thenout. The voice described what you should hear. If you
heard the opposite, your speakers were out of phase.]not color coded) is to place the two speakers close
P.S. The more standard phasing test for speakers (assuming your wires are
together, play music with considerable bass content, then reverse theleads to one speaker. The wiring with maximum perceived
bass is the correct one.
