3. INTRODUCTION
The SMS3 and SMS3W are a compact two-way loudspeaker system designed for constant-
voltage. The 4.75” (120 mm) carbon ber woofer, in combination with a 0.5” (13 mm) mylar dome
tweeter mounted on a 110° x 100° constant directivity horn, provide natural, smooth sound
reproduction, ideal for use in business music systems and indoor/outdoor background music
applications. The passive crossover is designed to reduce heat dissipation and optimize the
power response of the loudspeaker. Connections are made to recessed, color-coded spring-loaded
terminals. The enclosure is constructed of high-density plastic, with M6 threaded inserts for use
with the optional mounting hardware, and includes a protective perforated steel grille.
