Coverage Angles

102M/122M/152M- These models are equipped with 60° conical waveguides. HF coverage remains constant regardless of cabinet orientation.

102W- Before mounting the loudspeaker, determine the mounting orientation and desired coverage angles. As supplied from the factory, the loudspeaker’s coverage angles are 150° (horizontal) x 50° (vertical) with the cabinet oriented vertically. The waveguide can be rotated to interchange the coverage angles.

Rotating the Waveguide to Alter HF Coverage Pattern (102W only)

1- Remove the grill. It is held in place by eight cap head screws.

2- Remove the four waveguide retaining screws. A #2-size Phillips screwdriver is recommended.

3- Reach into the waveguide’s port and pull gently to remove the waveguide. Be careful not to damage the connections, wiring, or the gasket between the waveguide and the cabinet. The aluminum spacer ring must remain in place.

4- Rotate the waveguide 90° clockwise or counterclockwise and set it back in place. Make certain the wiring is not stressed or pulled loose from its connections when rotating the assembly.

5- Before reinstalling the waveguide mounting screws, lift the assembly a small distance and make sure that the gasket and spacer ring are properly in place. Reposition, if required. Set the waveguide in place and install the screws. We recom- mend the use of removable thread sealant to prevent the screws from loosening. Do not overtighten.

6- Replace the grill. We recommend the use of removable threadlocker to prevent the screws from loosening. Do not over- tighten.
