The two-way SMS4990 (4 x 4-inch LF, 1 x 1.3-inch HF, 90-degree by 90-degree coverage pattern) SMS4990 advances the state-of-the-art for small loudspeaker technology in providing high quality sound and controlled directivity. The design incorporates several innovative technologies developed by EAW for much larger professional loudspeakers. 4 LF drivers are configured in a precise arrangement to provide excellent pattern control and coherency below the LF/HF crossover. In addition, the LF drivers couple at lower frequencies providing the LF output of a much larger driver without sacrificing sound quality through the crossover region. The custom, high power HF driver complements the LF subsystem throughout the critical speech range. The SMS4990 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. For basic installations, SMS loudspeakers are also provided with U-brackets.
