4. Setup and Installation
4.1 Speaker Placement
Consider the following when choosing speaker locations:
- For optimal sound dispersion, place speakers at ear level when seated, if possible.
- Space speakers evenly to create a balanced sound field.
- While weather-resistant, installing under eaves or a covered patio will protect speakers from direct heavy rain and prolong their lifespan.

4.2 Mounting the Speakers
The AP450 speakers come with flexible mounting brackets that allow for vertical or horizontal installation. Follow these steps:
- Attach Brackets: Secure the mounting brackets to your chosen surface (wall, ceiling, etc.) using appropriate screws and anchors (not included). Ensure the surface is strong enough to hold the speaker's weight.
- Position Speaker: Align the speaker with the bracket. The speaker can be rotated and tilted to direct sound.
- Secure Speaker: Use the provided knobs or screws to firmly attach the speaker to the bracket and lock it into the desired angle.

4.3 Wiring Connections
Before making any connections, ensure your amplifier or receiver is turned off.
- Prepare Speaker Wire: Strip approximately 1/2 inch (12mm) of insulation from the ends of your speaker wire. Twist the bare strands tightly.
- Connect to Speaker: Locate the binding posts on the back of the AP450 speaker. Connect the positive (+) terminal of the speaker to the positive (+) terminal of your amplifier, and the negative (–) terminal of the speaker to the negative (–) terminal of your amplifier. Ensure no stray wire strands are touching between terminals, which could cause a short circuit.
- Connect to Amplifier: Repeat the process for the other end of the speaker wire, connecting it to the corresponding speaker output terminals on your amplifier or receiver.
