The two-way SMS2990 (4 x 3-inch LF, 1 x 1.3-inch HF, 90-degree by 90-degree coverage pattern) incorporates proprietary Theta Technology™, with the LF drivers configured in a precise arrangement to provide excellent pattern control and coherency below the LF/HF crossover. The LF drivers also couple at lower frequencies, providing LF output of a much larger driver without sacrificing sound quality through the crossover region. The SMS2990 is designed for surface mounting using the proprietary Clip-Fit™ system. All connections for the loudspeaker are contained within the Clip-Fit wall-mount unit via a single Molex connector, with the wall-mount unit pre-mounted at the preferred position on a wall. The installer then just “clips” the loudspeakers onto the Clip-Fit arm, and in one motion, the audio connection is terminated and the loudspeaker is live. The wall-mount unit offers a pan/tilt positioning range for precise aiming. The wall-mount unit offers a pan/tilt positioning range for precise aiming.
