Top left woofer replacement:

  11

 

Six screws need to be removed from 

each side of the front of the grill (twelve 

screws total) using the phillips head 

screwdriver. This grill has a tendency to 

want to “pop” off, so please be sure to 

hold it in place with one hand or arm 

while removing the screws with your 

free hand. In addition to the grill, the 

screws also hold the decorative trim. The 

trim should be removed, too. Keep the 

twelve screws in a safe place.

Eight screws need to be removed 

from the woofer using the phillips head 

screwdriver. Once the screws are 

removed, the woofer may be loosened 

by prying a fl at head screwdriver in 

between the cabinet and the woofer; 

a good place to start is in the notches 

located just above the horn assembly 

and below the woofer (as pointed out 

by the arrows in the picture above). 

Also note the “tinsel dressing teardrops” 

(circled above) which are facing down. 

The woofer should be placed back the 

same way. It is for visual consistency. 

More importantly, the cables from the 

printed circuit board to the woofer 

terminals are quite short; it probably 

would not work otherwise. The eight 

screws should be kept in a safe place.
