REQUIREMENTS FOR MOUNTING

OPTION 2 – RETROFIT/PREEXISTING CONSTRUCTION: Use the S4RFB bracket. Mount the S4RFB to the wall surface and secure it to studs behind the wall. Attach the speaker via mounting flanges to the appropriate recessed distance. The S4VC and S4HC require a minimum 6" wall depth. The S4Ai requires a minimum 4" wall depth (see Figures 18, 19 and 20).

NOTE: Do not attempt to install any type of mounting bracket other than the S4PCB, the S4RFB, or any other bracket that JBL may supply for these speakers in the future. Drilling holes in the product or improperly installing mounting brackets may void your JBL warranty and cause a safety hazard.

A JBL factory-authorized custom installer can install appropriate brackets. Contact JBL and your installer/dealer for additional information.
