The Sound Town ZETHUS Series ZETHUS-218S is a high-performance passive subwoofer designed for professional audio applications. This robust subwoofer features two 18" high-power transducers, each equipped with a 4" voice coil and an aluminum demodulating ring, ensuring the massive power handling capacity of 1600W RMS and 3200W program output. The result is deep, rich, and punchy bass that elevates any audio experience.

Constructed for the rigors of the road, the ZETHUS-218S's cabinet is built from premium multi-layered birch plywood and shielded by a 14-gauge steel grille with anti-corrosion treatment and a durable textured coating. This tour-grade build makes it resilient enough to endure extensive touring and harsh environments.

Integrate seamlessly with ZETHUS-210B or ZETHUS-208BV2 full-range array speakers using the optional ZETHUS-SF1 mounting frame (sold separately) to fit your audio needs. It delivers precise and immersive audio performance suitable for a variety of venues including stages, bars, ballrooms, restaurants, places of worship, and convention centers.

The ZETHUS-218S is engineered with both passive and bi-amp modes, allowing for flexible operation and optimal sound customization. In bi-amp mode, each woofer can be driven by its own dedicated amplifier channel, which increases power efficiency, reduces strain on amplifiers, and allows for precise sound tuning.

Designed for versatility, the ZETHUS-218S supports both ground and stacked configurations, catering to the most demanding concert and touring applications. Whether you're outfitting a concert hall or setting up a local venue, the ZETHUS-218S subwoofer brings professional-grade bass performance and reliability to every event.
