The EAW SM400 is a high-power, two-way passive stage monitor engineered to deliver exceptional clarity and substantial output for performers on large stages where standard single-driver monitors are insufficient. This robust wedge is designed with dual 12-inch low-frequency drivers and a high-frequency compression driver to provide the immense headroom and sonic detail required by drummers, vocalists, and instrumentalists in major touring, festival, and large theatrical productions. Its design focuses on delivering a focused, articulate sound directly to the performer, with enough low-end punch to feel bass and kick drum while maintaining crystal-clear midrange and high-frequency definition for vocals and intricate instrumentals. The wide, trapezoidal wedge shape ensures stability on stage and provides an optimized acoustic angle to project sound upward toward the performer's ears.

Acoustic performance is achieved through a sophisticated component layout where the dual woofers handle the powerful low and lower-mid frequencies, delivering the physical impact and fullness essential for monitoring on loud stages. A high-output 1.75-inch or 2-inch compression driver, mounted on a wide-dispersion horn, reproduces detailed highs with controlled coverage to minimize stage wash and provide consistent tone for the primary user. The passive crossover network is meticulously designed to manage the complex load of the dual woofers and seamlessly integrate the high-frequency driver, ensuring phase coherence and protecting the components from overload. This configuration results in a monitor capable of extremely high sound pressure levels with low distortion, giving performers the confidence to hear themselves clearly even in the most demanding acoustic environments.

Constructed for the extreme physical and sonic demands of professional touring, the SM400 features a massively braced multi-ply birch plywood enclosure with a reinforced, angled baffle. The exterior is covered in a rugged, textured coating or durable carpet to withstand constant handling, scuffs, and stage wear. It includes multiple heavy-duty steel handles for transport and reinforced corners for added durability. The input panel features dual NL4 connectors for daisy-chaining and flexible amplifier connection options. The combination of its brute-force dual-woofer design, precise high-frequency reproduction, and road-proven construction makes the EAW SM400 a top-tier choice for audio engineers and performers who require a monitor capable of delivering pristine, high-volume sound on the world's biggest stages.
