Customers often ask us if they need special installation mounting brackets on their OSD ceiling speakers. For the most part the answer is no and here’s why. All our in-ceiling speakers feature a dog leg (L-shaped) mounting system that is part of the frame. Before you install the speakers, remove the grille and you’ll see several the mounting screws near the front frame. These screws need to be loosened to activate the dog leg clamps. Use a screwdriver to loosen (turn to the left) these screws and the clamp will come loose. When the speaker is in position in the ceiling, tighten (turn to the right) the screw and the speaker will be secured to the ceiling. However! These new construction brackets still offer several advantages in certain situations. For instance, they offer additional support of the wall or the ceiling by creating a stable base for your speaker. Meanwhile, they provide a template for cutting a mounting hole so that you can achieve precise placement down to a fraction of an inch. Whether you're watching a movie in your home theater or listening to the sweet sounds of your outdoor speakers, these accessories may be able to enhance your sound and provide the additional support you need for effective installation.
