MECHANICAL INSTALLATION 110SR
NEW / EXISTING CONSTRUCTION INSTALLATION PROCEDURES:
Before You Begin:
Please read and understand all of these instructions thoroughly before beginning any work.
Note that all construction work for the installation of all Tannoy products must be done to local building codes by
qualified, licensed installers. A local building inspector should approve any overhead installations. Always use safety
goggles when cutting material using a Rotozip™ . Tannoy assumes no liability for cause and effect of improper
installation work.
Your Package Includes:
• 110 SR subwoofer system
• 11 piece supplied screw package
• Pre-Installation ring (PIR - SOLD SEPARATELY)
• Individually packaged grille
Tools/ Parts Required:
The following is a list of suggested materials and tools. Your needs may differ slightly at each site:
• Rotozip™ cutout tool and Guidepoint™ bit
• 2-1/2” #8 wood screws
• Cordless screw gun
• Combination square and /or tape measure
• Additional 2” x 4” lumber, in 24” pieces
• Trim saw (optional)
Site Preparation and Installation Procedures:
Please note that the 110SR is designed for installation in a ceiling with exposed ceiling joists. The PIR must be secured
to the support structure; drywall alone will not support the weight of the subwoofer. Make certain that there is sufficient
clearance above the joist (minimum 12”) for the subwoofer installation.
Please refer to the photographs as a guideline for installing the PIR into a wood joist or steel stud ceiling.
1) (Fig. 1) Measure the locations for two 24” strips of 2” x 2” or 2” x 4” blocking. These must be used in order for
secure mounting to the PIR with 2-1/2” #8 wood screws. Use a combination square to measure the thickness of
the PIR (approx. 5/8”), and then transfer the measurement to the joist.
2) (Fig. 2) Screw the blocking to the joist with several evenly spaced screws. (Fig. 3) Fasten the PIR similarly to
the blocking. Note that there are no pre-drilled holes; use the wood screws to go directly through the PIR,
keeping a 1” clearance from any “T”-nuts. Note: the PIR must be installed with “T”-nuts on the top side. The
PIR is clearly marked for your safety and convenience.
