3. INTRODUCTION
The SMS4 and SMS4W are a compact two-way loudspeaker system designed for constant-
voltage. The 5” (130 mm) carbon fiber woofer, in combination with a 0.5” (13 mm) mylar dome
tweeter mounted on a 110° x 110° 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.
