Optional Tweeter or Midrange Attenuation
To attenuate the tweeter or midrange, remove the jumper(s) and install a resistor.
The 1 ohm resistor is the standard tweeter and midrange resistor values. Other tweeter and midrange resistor
values are available from your Magneplanar dealer.
In addition to the tweeter resistor, installing the 1 ohm midrange resistor will also provide a "warmer" balance.

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.
