SMS4990 Spec Sheet

SMS 4990

2-Way Surface Mounted Loudspeaker

DESCRIPTION

The 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.

These provide the SMS4990 with the directional performance, wavefront coherency, output levels, and sound quality normally associated with much larger and more expensive loudspeakers.

The 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 result of these driver configurations is an extended range of pattern control and coherency that is not generally associated with loudspeakers of this size.

The SMS4990 is designed for surface mounting using the Clip-Fit™ wall bracket. The Clip-Fit bracket provides both the mechanical and electrical connections to the loudspeaker. This allows the loudspeaker mounting and wiring to be pre-installed on the job site. The loudspeaker is then simply mounted to the Clip-Fit bracket in one operation that provides both the mechanical and electrical connections.
