It ships ready to hang from a single point and can be panned, tilted and rotated to meet Dolby Atmos aiming requirements. With an optional wall-mount kit it also works for side and rear surrounds.\u003c\/p\u003e\n\n\u003ch2\u003eHow does the Dolby SLS MA390C work?\u003c\/h2\u003e\n\u003cp\u003eA 300 W, 12-inch coaxial driver with a 1.75-inch coaxially mounted high-frequency section and a passive crossover sits inside the sphere. Coverage is 90° conical, sensitivity is 96 dB, and calculated maximum output is 121 dB continuous and 124 dB program at one metre, across 60 Hz to 20 kHz.\u003c\/p\u003e\n\u003cp\u003eThe speaker ships ready to install from a single point, typically all-thread, and adjusts in pan, tilt and rotation without extra brackets. Two ceiling-grid tile mounts are available. The FCT-24 flat tile bridge mounts the speaker below the grid, while the RCT-24 recessed tile bridge raises it into the ceiling to minimize projector sight-line issues. Each replaces a 2 ft x 2 ft ceiling tile, and the grid carries the load with only a simple safety cable to the structure.\u003c\/p\u003e\n\u003cp\u003eFor side and rear surrounds, the WMA-15 wall-mount kit is available.
