It's really a matter of aesthetic preference. These flush mounted speakers are hardly noticeable; that is until they're playing. Our Architectural Ceiling Element (ACE) Trimless speakers do not include the 3/4-inch trim you typically see around in-wall and ceiling speakers. The micro flange grilles are attached by extremely powerful magnets that stay put for quick and easy installation. Adds less visual impact on your architectural audio installation.

Customers often ask us if they need special installation mounting brackets on their OSD ceiling speakers. 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.

OSD Audio in-wall subs are passive devices, meaning they do not include a built-in amplifier like you would find in our active "box" subs. You will have to provide additional power, specifically a subwoofer amplifier, to drive it. We recommend our SMP200 dedicated subwoofer amplifier that features 120 watts (mono) and front panel controls, phase switch, frequency control knob (35 Hz to 160 Hz) and volume control.
