4.1 Speaker Placement
For optimal sound performance, consider the acoustics of your chosen location. Speakers should be placed to create a balanced sound field. Ensure the mounting surface is sturdy enough to support the weight of the speakers.

4.2 Mounting the Speakers
- Attach Brackets: Secure the U-shaped mounting brackets to your desired surface using appropriate screws (not included) for the material (wood, masonry, etc.). Ensure the brackets are level and spaced correctly for each speaker.
- Mount Speakers: Slide the speakers onto the mounted U-brackets. The adjustable design allows for easy attachment.
- Adjust Angle: Once mounted, adjust the swivel brackets to direct the sound as desired. The brackets allow for 90-180 degree versatile swivel. Fasten the speakers securely once the angle is set.

4.3 Wiring Connections
Connect the speaker wires to the quick-connect terminals on the back of each speaker. Ensure correct polarity (positive to positive, negative to negative) when connecting to your amplifier. The red terminal is typically positive (+), and the black terminal is negative (-).
These speakers are passive and require an external amplifier or receiver. Connect the other end of the speaker wires to the corresponding speaker outputs on your amplifier.

6. Maintenance
To ensure the longevity and performance of your Herdio outdoor speakers, follow these maintenance guidelines:
- Cleaning: Wipe the speaker enclosures with a soft, damp cloth. Avoid using harsh chemicals or abrasive cleaners.
- Grill Care: The rustproof mesh grills can be removed for cleaning if necessary. Ensure they are dry before reattaching.
- Weather Protection: While designed for all-weather use (IP44 rated), prolonged exposure to extreme conditions (e.g., direct heavy rain, snow, or extreme temperatures) should be minimized if possible to extend product life.
- Connection Check: Periodically inspect speaker wire connections for corrosion or looseness, especially in outdoor environments.
