The Electro-Voice Sx300 is a versatile, high-performance 12-inch two-way passive loudspeaker designed to deliver full-range sound reinforcement for live music, portable PA, and installed applications. This enclosure integrates a 12-inch woofer with a 1.5-inch titanium diaphragm compression driver, coupled to a wide-dispersion horn, and managed by a precision passive crossover network. This configuration is engineered to provide a balanced frequency response with robust low-end punch, articulate midrange for vocal clarity, and detailed high-frequency reproduction, making it suitable as a main speaker for small to medium venues, a powerful stage monitor, or a reliable component in fixed installations.

Constructed for durability in professional environments, the cabinet is built from multi-ply plywood and finished with a textured, scratch-resistant coating that withstands frequent handling and transport. Its trapezoidal shape allows for flexible deployment as a standalone cabinet, as part of a stacked system, or as a stage monitor when placed on its side. The design incorporates integrated handles, robust steel corners, and multiple mounting points, including a pole socket and flyware attachments, providing practical options for stand mounting, wall mounting, or flying. These features prioritize both acoustic performance and the practical needs of touring crews and installers.

Sonic performance is characterized by high sensitivity, substantial power handling, and a broad, even dispersion pattern that ensures consistent coverage across the audience area. The loudspeaker's ability to achieve high sound pressure levels with clarity and impact makes it a reliable choice for sound engineers and musicians who require a versatile and dependable full-range solution. As a foundational component in many professional audio systems, the Sx300 offers a balance of power, clarity, and road-ready construction, delivering reliable performance for a wide range of sound reinforcement challenges.
