Adamson E218 Dual 18″ Subwoofers (Set of 3)

The Adamson E218 Dual 18″ Subwoofer is a powerful low-frequency reinforcement solution designed for large-scale events and high-performance installations. Part of Adamson’s E-Series, it is built to deliver deep, impactful bass that complements the rest of the E-Series speaker lineup, particularly in environments that require significant low-end extension. With its dual 18-inch Kevlar Neodymium drivers, the E218 subwoofer excels in providing consistent, punchy bass while maintaining clarity and precision, even at high sound pressure levels. It is widely used in concerts, festivals, stadiums, and other large venues where robust bass response is essential.

At the core of the E218’s design are two 18-inch Kevlar Neodymium drivers, chosen for their durability, efficiency, and ability to handle extreme sound pressure levels without distortion. Kevlar, known for its strength and flexibility, enhances the subwoofer’s resilience, particularly in demanding live sound environments. The subwoofer has a frequency response that extends as low as 29 Hz, ensuring it can reproduce deep, chest-thumping bass that adds depth and power to any sound system. With a maximum SPL output of 143 dB, the E218 can effortlessly fill large spaces with immersive, high-impact low frequencies, making it an ideal choice for events where strong bass presence is a priority.

The E218 is housed in a rugged, tour-ready enclosure constructed from marine-grade birch plywood, which provides excellent resistance to the elements and rough handling. The enclosure is designed with both performance and portability in mind, featuring integrated handles and a durable finish that protects the unit during transport and setup. The subwoofer’s design also includes a bass reflex configuration with optimized port geometry, ensuring smooth airflow and reducing port noise, which enhances overall efficiency and sound quality. This configuration allows the E218 to deliver deep bass without compromising clarity or introducing unwanted distortion, even at high volumes.

The Adamson E218 Dual 18″ is highly versatile in its deployment options. It can be used in both flown and ground-stacked configurations, depending on the needs of the venue or event. When paired with Adamson’s E12 or E15 line array systems, the E218 subwoofer provides a seamless low-end extension, creating a full-range audio experience that covers the entire frequency spectrum. The subwoofer is also compatible with Adamson’s Blueprint AV software, which allows sound engineers to model and predict the system’s performance in various environments, ensuring optimal sound coverage and consistency. Additionally, multiple E218 units can be arrayed together for increased output, making it a scalable solution for events of all sizes.
