Selecting Power Levels
The front-mounted selector switch (under
grille) is used to set the appropriate power
level or impedance for your system. Using a
small, flat-blade screwdriver, turn the knob
until the slot points to the power level you
require.
70V/
100V Systems
Both power setting scales for 70V and 100V
systems are labeled on the speakers. On the
100V scale, the last position clockwise is
marked with a symbol. Do not use this
position in 100V systems.
16 Ω
Systems
The fully counterclockwise position of the setting switch is the 16-ohm position.
This setting is suitable for use with low-impedance amplifiers that typically sup-
port 4- or 8-ohm speakers. The speaker’s higher, 16-ohm impedance makes it
easier to combine multiple speakers into series-parallel networks while keeping
the total system impedance at a level suitable for low-impedance amplifiers.
Speaker Grille Installation &
Removal
Installation
The speaker grille fits tightly! Push the speaker
grille in until it can go no further. Then, slap
around the edge of the grille to seat the grille.
The grille is properly seated when it is flush with
the edge of the bezel.
Removal
Insert a pocketknife blade between the grille and
the bezel about

" deep and then gently pry the
grille upwards. Do this in multiple places around
the circumference of the grille.
