Installation and Safety Guidelines

This product is intended for installation by professional installers only! This document is intended to provide professional installers with basic installation and safety guidelines for Bose RoomMatch® Utility loudspeakers in typical fixed-installation systems. Please read this document before attempting installation.

WARNING: All Bose ^® products must be used in accordance with local, state, federal and industry regulations. It is the installer's responsibility to ensure installation of the loudspeakers and mounting system is performed in accordance with all applicable codes, including local building codes and regulations. Consult the local authority having jurisdiction before installing this product.

WARNING: Unsafe mounting or overhead suspension of any heavy load can result in serious injury and equipment damage. It is the responsibility of the installer to evaluate the reliability of any mounting method used for their application. Only professional installers with the knowledge of proper hardware and safe mounting techniques should attempt to install any loudspeaker overhead.

Guidelines for Permanent Installation of RoomMatch Utility Loudspeakers

The installation information contained in this document is only a general guideline and cannot, as such, represent all requirements and precautions. Accordingly, anyone using this material assumes all liability and is expressly responsible for the safety of all loudspeaker array designs and mounting configurations applied in practice.

1. Prior to the installation of any overhead loudspeaker, a licensed professional engineer must approve the location and method of attachment to the building structure and confirm they are consistent with all building codes and regulations. Ensure the mounting surface and the method of attaching the loudspeaker system to the surface is capable of supporting the total weight of the system. A safety factor of 10:1 is recommended.
2. Obtain all mounting system components from reputable manufacturers. Select a mounting system appropriate for your loudspeaker system and its intended application. We recommend Bose mounting accessories when available. A licensed professional engineer must review the design and fabrication of any custom mounting hardware.
3. Bose RoomMatch Utility loudspeakers feature integrated M8 threaded inserts to facilitate loudspeaker mounting by professional installers. Do NOT use SAE 5/16" size threaded hardware! Use only metric hardware. Fasteners should be metric Class 8.8 (load bearing rated) or equivalent. Unmarked (not rated for load bearing) fasteners should not be used.
4. Use lock washers or a locking compound intended for hand disassembly, such as LOCTITE ^® THREADLOCKER BLUE 242 ^® compound, for a vibration resistant assembly.
5. Fasteners should be tightened using torque of 15 to 20 foot-pounds (21 to 28 Newton-meters). Over-tightening the fasteners could result in irreparable damage to the cabinet and create an unsafe assembly.
6. Do not attempt to alter the threaded attachment points or re-thread the attachment points to accommodate any other thread size or type; doing so will compromise the safety while permanently damaging the loudspeaker.
7. Use a safety cable, separately attached to the cabinet, at a point not in common with the load bearing attachment points of the mounting system to the loudspeaker. This is recommended even if not required by local regulation. Consult a licensed professional engineer or a rigging professional for proper design and installation.

CAUTION: Installed loudspeakers require regular inspection and routine maintenance to ensure proper function and safe operation. Inspect mounting hardware and attachments for signs of corrosion, bending or any other condition that may decrease the structural integrity. Immediately replace worn or damaged components.

CAUTION: Make no modifications to the loudspeakers or mounting accessories. Unauthorized alterations may compromise safety and could result in damage, injury, or death.

CAUTION: Never exceed 1 RoomMatch Utility loudspeaker using the included U-bracket. Additionally, never exceed 1 RoomMatch Utility loudspeaker using the rear-enclosure M8 threaded inserts to attach to any supporting surface.

CAUTION: This product must be used indoors.
