How to use

Locate a suitable mounting position in the ceiling clear of joists, ducts and wiring. Cut an opening sized to the speaker dimensions, following any template supplied with the product. Connect the speaker to an amplifier or audio source with matching impedance and appropriate power output, ensuring correct polarity on the speaker terminals. Insert the speaker into the ceiling opening and secure it according to the mounting clamps or fasteners provided. Adjust playback levels from the connected amplifier or source to avoid clipping and ensure even coverage across the intended area.

Recommendations

For reliable operation, pair the speaker with an amplifier that can deliver clean power within the speaker's rated range and observe the 8 Ω impedance to avoid mismatching. Position speakers to provide even coverage and avoid placing them too close to HVAC vents or direct airflow. For improved speech intelligibility in public address use, test placement and volume settings before regular operation.
