Why use brackets or back boxes for in-ceiling and in-wall speakers?

Pre-Construction Brackets are used for new home construction or remodeling before sheetrock is hung. Brackets allow you to precisely position where speakers will be installed. The aluminum bracket wings can be stapled, nailed or screwed to studs or joists. Back boxes are designed specifically to enhance the speaker's performance; they utilize the ideal air volume for the speaker and act as a sound chamber, directing the critical sound to the sweet spot. Back boxes can also reduce the sound going to other rooms/floors up to 10dB and provides one-hour fire break protection.
