3.1 Securing the CS128LF
It is required that the speaker system is secured to the building structure.
About this task
The following tools are needed to secure the Dolby CS128LF:
• 6 mm hex driver or wrench
• BKT.FLR brackets
• Installer-provided serviceable thread-locking compound (recommended)
• Installer-provided acoustic or non-hardening caulking (recommended)
Procedure
1. Determine the proper placement of the system.
Note: Check with local building codes, and always refer the installation to a qualified professional.
2. Remove the four M10 bolts from the bottom sides of the CS128LF speaker cabinet, as shown in the
following figure. These bolts are pre-installed in the CS128LF cabinet.
3. Reinstall the M10 bolts with the M10 washers, included with the BKT.FLR kit, securing the BKT.FLR
brackets, and then tighten the M10 bolts to 12 Nm (8.9 ft-lb, 106 in-lb).
4. Secure the CS128LF to the building structure with installer provided mounting hardware.
Note: Proper selection and installation of mounting hardware is the exclusive responsibility of the
installer. We recommend using M10 bolts and a serviceable thread-locking compound (for
example, Loctite 243). We also recommend applying acoustic or other non-hardening caulking to
the bottom side of the bracket to isolate speaker vibration from the building structure.
Caution: Vibration from this type of speaker system is high and may cause cabinets to shift.
Failure to secure the bottom speaker cabinet to the building structure may result in the speaker
system tipping or falling, which may cause damage or injury.
Caution: Dolby disclaims any liability, including damage or injury, for the use of non-Dolby
supplied mounting hardware, supports, and brackets. Any modification to the speaker system (for
example, mounting by drilling holes into the speaker system) will render the product warranty null
and void.
Attention: The Dolby Speaker System 128 was designed to be placed as close to the screen as
possible, within 5-7 cm. When aiming the system, angling of the CS128MH may require that the
speaker system be set back from the screen to accommodate proper tilting and aiming
