Use with new construction where drywall has not yet been installed. Attach bracket across studs in desired location and leave the hole-cutting to the drywall installers. (NOTE: This bracket designed for use on joists or studs having 21" or less on-center spacing.)
Just nail this sheet metal bracket between the studs or joists before the drywall goes up. Then the drywall installers will cut the speaker hole for you in exactly the right spot! This bracket is ONLY for use with the round, Multi-Purpose MP-R50 speaker.
