Pre-installation brackets are a great way to reserve the location of the speaker during the construction of your home so that potential obstructions don’t become an obstacle once the drywall is installed. These brackets also serve as a helpful guide to cut the required speaker opening once the drywall is in place. Please note that pre-installation brackets are not required to install in-ceiling or in-wall speakers, they merely serve as a helpful planning tool and guide for cutting the wall surface.
