Unpack and inspect contents. Ensure mounting location can support speaker weight.
WARNING! Speaker is heavy; use proper lifting techniques or multiple persons. Ensure mounting structure is secure.
Configure system with compatible amplifier and bass modules.
CAUTION! Do not overpower speakers. Match amplifier power to speaker ratings.
No user controls on speaker. All adjustments made via external amplifier, crossover, or controller.
Connections: Terminal cup with screw terminals or NL4 Speakon connector (model dependent).
Polarity: Ensure (+) and (-) connections match amplifier output for proper phase alignment.
Mounting: Integrated brackets allow for adjustable angle mounting. Use appropriate hardware for surface.
Use professional-grade speaker cable of appropriate gauge for run length.
Tip: Use balanced, high-quality cables to minimize signal loss and noise.
Designed to work with Bose 502B bass modules and 502C controller for full-range sound.
WARNING! Do not operate without proper crossover protection. High-frequency drivers can be damaged by low-frequency content.
The 90° x 40° coverage pattern provides controlled dispersion for reduced reflections and even coverage.
Placement: Aim speakers to cover listening area without pointing at reflective surfaces.
Arraying: When arraying multiple cabinets, align them carefully to maintain consistent pattern control.
Height: Mount at appropriate height to cover audience area effectively.
Regular inspection ensures long-term performance.
CAUTION! Do not use solvents, abrasives, or high-pressure water. Do not open enclosure.
