Lifetime Tech Support

Metal Back Boxes are designed to enhance the speaker's performance. It utilizes the ideal air volume for the speaker, and acts as a sound chamber, directing the critical sound to the sweet spot. It also reduces the sound going to other rooms/floors up to 10db, and provides one hour fire break protection.

No matter what your musical preference is, you expect only the best sound quality from your OSD Audio in-ceiling speakers. One of the key steps in achieving this is to contain the sound from the speaker to your room, as opposed to your ceiling cavity. This back box does just that – ensuring that the sound waves don’t escape, but also ensuring that they’re distributed correctly, therefore improving the overall sound quality.

Using this back box will ensure that the sound waves are directed downwards, and don’t travel from one floor to another. This can be particularly useful where the space between floors is minimal, meaning that you can jam to Slayer without disrupting your wife’s listening of Bach.
