14 Optional Tweeter Attenuation
There are two principal reasons for needing to attenuate the Magneplanar
Quasi-Ribbon Tweeter and Super Tweeter:
A. Pop or rock recordings often exhibit a pronounced rise in the treble
region.
B. The Magneplanar Quasi Ribbon Tweeter is very efficient in its total energy
dispersion. If the surrounding walls are exceptionally reflective, 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.
The 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.

measurements, frequency response specifications may be stated by most
manufacturers without reference to measurement techniques and/or specific
locations in rooms. Magneplanar loudspeaker frequency response
specifications are average performance levels that may reasonably be expected
in normal installations.
