14 Optional Tweeter Attenuation
Th
ere are two principal reasons for needing to attenuate the Magneplanar
Quasi-Ribbon Tweeter and Super Tweeter:
A. Pop or rock recordings o
ft
en exhibit a pronounced rise in the treble
region.
B.
Th
e Magneplanar Quasi Ribbon Tweeter is very e
ffi
cient in its total energy
dispersion. If the surrounding walls are exceptionally re
fl
ective, the overall
perceived acoustical balance will be tipped towards a "hot" high end.
Attenuation is performed through insertion of a resistor in place of the jumper.
Th
e pair of 1.2 ohm resistors will attenuate the tweeter 1-2 dB. Other values are
available from your Magneplanar dealer.
16 Maintenance
Light vacuuming of the grille cloth is possible.

* Because there are no universally accepted methods for loudspeaker
measurements, frequency response speci

cations may be stated by most
manufacturers without reference to measurement techniques and/or speci

c
locations in rooms. Magneplanar loudspeaker frequency response
speci
fi
cations are average performance levels that may reasonably be expected
in normal installations.
