K Phasing
a. Correct phasing between a "small" speaker, like the MMC 2, and the Bass
Panel is much more di ffi cult to detect than an out-of-phase condition
between le ft and right speakers. Th e ear/brain is less sensitive to phase
shi ft problems at lower frequencies and therefore, making it more di ffi cult
to detect. However, an out-of-phase condition between the MMC 2s and
the Bass Panel will result in a perceived frequency imbalance. A "suckout"
in the midbass due to an out-of-phase condition will subjectively make the
MMC 2s seem "bright" with excessive high frequencies.
b. Th e manufacturer of a full-range speaker gives considerable attention to
achieving correct phasing between the midrange and bass drivers. To get
the full bene
fi t of your high performance MMC 2s, we suggest that you get
the help of your dealer or a technician to ensure that the phasing between
the MMC 2s and your woofer is correct.
c. A Magnepan "Shaped" Pink Noise CD Test Disk is included with your
MMC 2s to assist in the proper phasing between the MMC 2s and your
Bass Panel.
Th e pink noise CD is "shaped" with a 9 db peak at 80-100 Hz.
Th is aids in the detection of an out-of-phase condition. Th is peak in the
midbass focuses the attention of the listener on this area of the frequency
response. When the MMC 2s are out of phase with the Bass Panel, this
peak will be reduced in level. Place the Magneplanar Bass Panel (or
subwoofer) next to the MMC 2s (It is much easier to detect an out-of-
phase condition when the "small" speaker is physically next to the Bass
Panel.)
