Overview
Inspection & Maintenance
WARNING: The loudspeaker and all mounting components must be inspected annually by a qualified
professional who is trained and certified in suspending loudspeaker systems. All rigging parts and
components used in the suspension of the loudspeaker system should be visually inspected for signs
of cracking, bending, water damage, corrosion, de-lamination, or any other condition that could
comprise the system's integrity and create a dangerous falling hazard.
Maintaining Weather Resistance
The MB210-WR compact subwoofer is water resistant and is rated IP55. To maintain water resistance, please
observe the following precautions:
1.
Before, during, and after installation, check the surface of the loudspeaker enclosure to ensure that the
factory-applied, weather-resistant coating has not been damaged.
2. During install, angle the loudspeaker at least 5° downward to reduce the potential of rain compromising the
performance of the loudspeaker.
3. All mounting holes must be sealed off with stainless steel screws (included with applicable accessories) or
the included plastic plugs (pre-installed).
4. The gland nut that secures the loudspeaker cable is factory sealed. Do not remove the gland nut or the
weather-resistant seal will be broken.
5. The loudspeaker is rated IP55, which means the grille is designed to withstand normal and wind-driven rain.
The grille is not designed to withstand direct spraying of water (i.e. from a hose).
CAUTION: If the above instructions are not observed, the weather-resistant integrity of your MB210-WR
compact subwoofer could be compromised.
