The Community IS8-218 is an I Series Subwoofer 800 dual 18" 3200W (4 Ohms) passive installation subwoofer in white. This subwoofer is well-suited for applications such as houses of worship, auditoriums, restaurants, meeting rooms, corporate A/V systems, arenas, stadiums, or any other application where additional reinforcement of low-frequencies is required.

I Series Subwoofer 800 loudspeakers provide exemplary acoustic performance, modular flexibility and elegant aesthetics for modern performance venues. Designed to support the goals of systems integrators and consultants both acoustically and mechanically, I Series Subwoofers provide a broad range of sizes and capabilities that can be specifically matched to the needs of any modern venue.

Each cabinet was carefully designed to provide matching heights, face widths and suspension point locations for seamless integration into flown arrays with I Series full-range models. The broad range of optional low profile fly rails, fly frames and modular array brackets reduces design and installation time while also providing improved aesthetics and nearly limitless integration possibilities.

The IS8-218 is a direct radiating subwoofer with large, balanced ports that provide optimal enclosure tuning and even air pressure distribution to the driver cones, reducing distortion and extending system longevity. Drivers are loaded into individual air volumes within the enclosure, isolating their performance from one another. This arrangement not only provides additional protection to drivers in case of failures, but also allows the designer to implement directional subwoofer techniques, like steered end-fire arrays and cardioid patterns, within a single enclosure when using any I Series dual driver subwoofer model.

Community IS8-218W Features:

• High-flux, linear neodymium motors with demodulation rings for very low distortion
