Coverage Angles
Before mounting the loudspeaker, determine the mounting orientation and desired coverage angles. As supplied from the factory,
the loudspeaker’s coverage angles are 90° (horizontal) x 60° (vertical) with the cabinet oriented vertically. The waveguide can be
rotated to interchange the coverage angles.

Maintain proper speaker and amplifier connection polarity throughout the entire system. All positive-marked
loudspeaker terminals should be connected to positive-marked amplifier output terminals. This will provide the
