OPTIONAL TWEETER ATTENUATION
There are two principal reasons for needing to attenuate the Magneplanar Quasi Ribbon
Tweeter:
A) Recordings, typically in the “pop” or “rock” vein, often exhibit pronounced rise in
the treble region.
B) The Magneplanar Quasi Ribbon Tweeter is very efficient in its total “energy
dispersion.” If the surround walls are exceptionally reflective, the overall
perceived acoustical balance will be tipped towards a “hot” high end.
Attenuation is performed through insertion of a simple non-inductive resistor in series
with the tweeter. See Figure 3.
Replace the left-hand jumper with the appropriate resistor to obtain the desired tweeter
attenuation. The pair of 1 ohm non-inductive resistors will attenuate the tweeter 1-2dB.
Other values are available from your Magneplanar dealer.
