New Construction Brackets for Ceiling and Wall Speakers are not required when you purchase OSD Audio speakers as all our speakers include dog-eared clamp mounting systems. However, these inexpensive brackets offer a number of advantages. They provide additional support of the wall or ceiling speaker and allow you to precisely place the speaker while providing a template to cut the mounting hole.
Metal Back Boxes are designed to enhance the speaker's performance by providing the ideal air volume for the speaker. It acts like a sound chamber, directing the critical sound to the sweet spot. Another benefit is that it reduces sound traveling to other rooms or floors, up to about 10db. |
