For Permanent Installation

WARNING:

Permanent installations involve the attachment of the loudspeakers to brackets or other mounting surfaces

for long-term or seasonal use. Such mountings, frequently in overhead locations, involve risk of personal injury if either the

mounting system or the loudspeaker attachment fails.

CAUTION:

Use only graded hardware. Fasteners should be metric Grade 8.8 minimum and should be tightened

using a torque not to exceed 50 inch-pounds (5.6 Newton-meters). Overtightening the fastener could result in irreparable

damage to the cabinet and an unsafe assembly.

Do not re-tighten these fasteners unless they are visibly loose. Lockwashers or a thread locking compound intended for

hand disassembly (such as Loctite

CAUTION:

The fastener should be long enough to engage no fewer than 8 and no more than 20 threads of the

attachment point. A fastener should protrude by 16 to 22 mm, with 18 mm preferred (

beyond the assembled mounting parts to provide sufficient threaded attachment to the loudspeaker. Using a fastener that is

too long may result in irreparable damage to the cabinet and, when overtightened, can create a potentially unsafe assembly.

Using a fastener that is too short provides inadequate holding power and may strip the mounting threads, resulting in an

unsafe assembly. Confirm that at least 8 full threads are engaged in your assembly.

CAUTION:

Do not attempt to alter the threaded attachment points. While SAE

similar in appearance to the metric M8, they are not interchangeable. Do not attempt to re-thread the attachment points to

accommodate any other thread size or type. Doing this will render the installation unsafe and will permanently damage the

loudspeaker. You may substitute

Bose

offers permanent mounting brackets for the safe use of these loudspeakers in such

installations. However, we realize some installations may call for use of other, custom-designed

mounting solutions or non-Bose mounting products. While Bose Corporation cannot be held

responsible for the proper design and use of non-Bose mounting systems, we offer the following

guidelines for the permanent installation of any Bose MB4 loudspeaker:

• Obtain your mounting system from a reputable manufacturer, and make sure the system

is specifically designed for the loudspeaker of choice and your intended use.

• Before using a custom-designed and fabricated mounting system, have a licensed

professional engineer review the design and fabrication for structural integrity and safety

in the intended application.

• Notice that all threaded attachment points on the bottom and top of each loudspeaker

cabinet have a metric M8 thread with at least 10 usable threads.

• Use a safety cable, separately attached to the cabinet at a point not in common with

the load-bearing attachment points of the bracket to the loudspeaker.

• If you are unfamiliar with the proper design, use, and purpose of a safety cable, consult

a licensed professional engineer, a rigging professional, or a theatrical lighting trades

professional.
