The Community IS6-218WR is an I Series Subwoofer 600 dual 18" 1400W (4 Ohms) passive installation subwoofer housed in a Weather-Resistant Light Grey Polyglas™ cabinet. Well-suited for application usage such as houses of worship, auditoriums, restaurants, meeting rooms, corporate A/V systems, arenas, stadiums, or any other application where extended low-frequency reinforcement is required, and is built for a lifetime of performance outdoors, as it's IP56-rated (per IEC 60529).

I Series Subwoofer 600 loudspeakers offer exemplary acoustic performance, modular versatility, and elegant aesthetics for contemporary performance venues. They're designed to support the goals of systems integrators and consultants both acoustically and mechanically, so are available in a broad range of sizes and capabilities that can be specifically matched to the needs of any modern venue.

Each cabinet has a been carefully engineered to provide matching heights, face widths, and suspension point locations for seamless integration into flown arrays* with I Series full-range models. The wide 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.

A direct radiating subwoofer, the IS6-218WR features large, balanced ports that provide optimal enclosure tuning and even air pressure distribution to the driver cones, which reduces distortion and extends system longevity. Drivers are loaded into individual air volumes within the enclosure, isolating their performance from one another. Not only does this arrangement provide 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.

About Community Weather-Resistant Models - A leader in understanding loudspeaker performance and durability in outdoor situations, Community utilizes PolyGlas construction for their weather-resistant I SERIES loudspeakers. This technique lets them make better quality enclosures at comparable prices while providing superior, longer-lasting protection than any fiberglass-covered wood loudspeaker, and they' re virtually immune to the destructive effects of moisture and temperature cycling. Additionally, manufacture and delivery times of PolyGlas I SERIES are similar to the wood versions, eliminating excessively long lead times.
