Speaker Placement

The included mounting bracket(s) allows for installation in locations such as:
•
Mounted to an exterior wall under a roof soffit minimizing exposure to sunlight/
rain (as shown in figure 1)
• On an exterior wall.
•
In a gazebo.
•
On a deck or railing.
Determining the Correct Distance Between Left and Right Speakers
Ideally you want to place the speakers far enough apart to achieve stereo imaging,
but not so far apart that you are unable to hear both speakers simultaneously in the pri-
mary listening area. As a rule of thumb, distance between your speakers should equal
50–75% of the distance from the listening area. For example, if you have a grilling or
lounging area 20 feet (6 meters) away, the speakers should be 10–15 feet (3–4.5
meters) apart.

Connections and Cables

Using Multiple Speakers on One Amplifier Channel
If you plan to use multiple speakers in series on a single amplifier channel, please
remember to check your amplifiers minimum safe speaker impedance load (ohms).
ML-45AW, ML-55AW, ML-65AW, and ML-75AW speakers are rated at
8-ohms per channel. Additional speakers connected to a single amplifier
channel will drop nominal impedance. To calculate the ohm load divide the
ohm rating of a single channel by number of speakers (i.e. 8-ohm rating / 4
speakers = 2-ohm load). Determine if your amp can handle the load and plan
accordingly.
