The baffle provides two methods of mounting:
1. The baffle can be suspended from a nail or hook by a "hanger" that is attached to the housing. See Figure 2.
2. The unit can be attached to a wall using two mounting bosses. Distance between the mounting boss holes’ center is 8.5". Remove gr ille and secure baffle to wall with screws. This mounting provides better low frequency response for music and a more secure attachment to the wall. See Figure 3.
