Step 5: Adjust Tap Selector
(Figure 10)
The tap selector switch is located on the
front baffle. Adjust the speaker to the
appropriate tap setting before installing the
grille. In some 70V/100V constant voltage
installations it is advisable to leave the
grilles off if final speaker audio level
balance adjustments are to be made later.
After the levels are adjusted the grilles can
then be installed.
Step 6: Attach the Grille (Figure 11)

Installation Note: Grille Safety
Feature
Bosch grilles features a unique safety
tether to prevent the grille from falling if
the grille is removed or comes loose
after installation.
First, install the grille’s safety tether by
pushing the grille fastener into the hole in
the front of the baffle (see Figure 11).
Second, press the grille into place until the
front of the grille is flush with the rim of the
baffle. Make sure the grille is securely
seated to prevent it from vibrating loose. If
you need to remove the grille, the easiest
way is to insert two bent paper clips or
other pointed objects into holes in the
grille, then apply slow even pressure to
pull down on the grille until that section of
the grille comes out slightly. Continue the
same procedure around the perimeter of
the grille, loosening a portion at a time
until the grille is removed.
