Product Overview
The Community IS8-218WR is a weather-resistant I Series Subwoofer 800 dual 18-inch passive subwoofer for high-output, low-frequency reinforcement outdoors or in. It is built for stadiums, arenas, larger houses of worship, and themed entertainment that need deep bass in demanding environments. Weather-resistant PolyGlas construction supports long-term outdoor exposure.
Product Description
The IS8-218WR is a compact, direct-radiating subwoofer with large, balanced ports that optimize enclosure tuning and even air pressure distribution to the driver cones, reducing distortion and extending system longevity. Drivers load into individual air volumes, isolating performance and allowing directional subwoofer techniques such as steered end-fire and cardioid patterns within one enclosure. High-flux linear neodymium motors with demodulation rings deliver very low distortion, and the matched-size enclosure with aligned suspension points integrates into flown arrays with I Series full-range models. The PolyGlas cabinet, marine-grade aluminum grille, and water-repellent fabric backing are built for a lifetime of outdoor performance.
Key Features
- Dual 18-inch drivers — Two 18-inch double-treated cones with neodymium motors and triple demodulation rings deliver very low distortion.
- High power handling — 3200W continuous power handling (12,800W peak) at 4 ohms supports demanding low-frequency reinforcement.
- Isolated driver volumes — Drivers load into individual air volumes, enabling directional subwoofer techniques within one enclosure.
- Array integration — Matched-size enclosure and aligned suspension points allow seamless integration into flown arrays with I Series full-range models.
- Flexible operation — Single or dual amp modes provide flexible power distribution across the two drivers.
- Weather-resistant — PolyGlas construction with marine-grade aluminum grille withstands outdoor exposure.
