5.2 Front grille
Removal
1.  Remove the four screws that attach the front grille to the 
baffle.
2.  Using a putty or butter knife, pry the grille outward and 
remove it. If the grille is stuck, gently pry along the sides 
in multiple locations until the grille becomes loose 
enough to remove. 
Installation
1.  Verify that the gasket along the top and bottom of the 
grille is still in place. If you are replacing the grille with a 
new one, install new gasket along the top and bottom 
of the grille to reduce vibrations between the grille and 
baffle. 
Note: Recommended gasket size is 1/2” width and at 
least 1/16” thickness.
2.  Fit the side edges of the grille in the space between the 
baffle and enclosure. Press down gently. Be careful not 
to bend the grille. If the grille does not fit in the space, 
the baffle may need to be realigned.
3.  Fasten the four screws that secure the grille to the baffle.
4.  Use a rubber mallet with a large head to gently press in 
the sides of the grille so that the grille is flush with the 
enclosure.

Removal
1.  To access the front baffle, the front grille must be 
removed. Follow the instructions in “5.2 Front grille” on 
page 16.
2.  Remove all screws around the perimeter of the baffle.
3.  Place the speaker on a work surface so that the baffle is 
face-down.
4.  Partially lift the enclosure away from the baffle assem-
bly.
5.  Disconnect the molex connector from the BOP. 
6.  You may now fully remove the baffle assembly from the 
main enclosure.
Installation
It’s recommend that the LF and HF transducers are installed 
before reinstalling the baffle to the main enclosure assem-
bly.
1.  Verify that the positive and negative terminals on the LF 
and HF transducers are connected securely to the wiring 
harness.
2.  Verify that the gasket is properly installed around the 
edge of the baffle.
3.  Reinstall all acoustic insulation in both the main enclo-
sure assembly and baffle assembly.
