4. Setup and Installation
4.1 Speaker Placement
For optimal sound projection, install speakers approximately 8 feet (2.4 meters) apart, slightly above ear level. The active speaker requires proximity to a power source. Passive speakers can be positioned further away (within 5 meters / 16.4 feet) but must connect to the active unit.

4.2 Mounting the Speakers
The speakers come with heavy-duty, 180° adjustable swivel brackets for precise positioning. Follow these steps for secure installation:
- Fixing Bracket Securely: Choose a suitable location on your wall. Use appropriate screws (not included) for your wall type to securely fix the mounting bracket.
- Mount Speaker: Attach the speaker to the bracket using the large plastic knobs supplied.
- Adjust Speaker Orientation: Point the speaker towards the listening area. Once the desired direction is set, tighten the knobs to secure the speaker. Slightly tilting the speakers downwards can help increase longevity and protect them from weather elements.
