Biamp Community IS8-218 High Power Dual 18-Inch Subwoofer (Black) -...
Product Overview
The Community IS8-218 is an I Series Subwoofer 800 dual 18-inch passive installation subwoofer for high-output, low-frequency reinforcement. It is built for houses of worship, auditoriums, arenas, and commercial A/V systems that need deep, clean bass extension. As part of the I Series, it integrates into flown arrays with matching full-range models.
Product Description
The IS8-218 is a 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 within the enclosure, isolating their performance and allowing directional subwoofer techniques such as steered end-fire and cardioid patterns within a single enclosure. The cabinet's matched height, face width, and suspension points enable seamless integration into flown arrays with I Series full-range models, and a broad range of optional fly rails, frames, and brackets reduces design and installation time. It operates in single or dual amp modes.
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.
Typical Applications
- House of worship
- Auditorium
