Overview: The Polk PB450 pre-construction brackets are designed specifically for the Polk Audio 500-LS and 50-RT in-ceiling speakers. These pre-construction brackets are used to designate the location of where the in-ceiling loudspeakers will be installed. The brackets define the holes that will need to be cut out. If you're building a new home, pre-construction brackets will make installing your in-ceiling speakers easier and more efficient. The included wings mount to the pre-construction brackets and to the ceiling studs, giving you a sturdy mount to install the speakers. Each bracket requires a cutout of 6.25" in diameter.
