Note: The rear resistor cover features a glass insert. Take care when installing or stor-
ing the cover to avoid breaking the glass.

Attach the top cover over the propagation delay hardware.

Section 4.10—Resistors

By removing the back cover of your Alexandrias, you may gain access to the resistor

plate (see Figure 23). These resistors serve several functions.

Note: Only Wilson Audio replacement resistors should be used in your Alexandrias.
Changing the value or brand
of resistor will have a delete-
rious affect on the sonic per-
formance of your loudspeak-
ers and may void your Wilson
Audio Warranty.

Midrange and Front Tweeter

Resistors

The Midrange Level and

Front Tweeter Level resistors

provide precise level matching

for the midrange and tweeter

drivers correspondingly. The

resistors also act as ultra high

quality fuses which open be-

fore a driver can be damaged

by excess power. See Section

6.0 for details in replacing

these resistors in the event one

of these two resistors is dam-

aged.
