Product Overview
The Biamp Community IS6-118WR is a weather-resistant medium-power single 18-inch installation subwoofer for outdoor and indoor low-frequency reinforcement. Part of the I SERIES Subwoofer 600 family, this compact direct-radiating sub-bass loudspeaker is ideal for distributed or concealed sub-bass in houses of worship, auditoriums, and multi-purpose venues, and is well suited to ground-stack applications.
Product Description
The IS6-118WR is a compact, direct-radiating single 18-inch subwoofer with large, balanced ports that provide optimal enclosure tuning and even air pressure distribution to the driver cone, reducing distortion and extending system longevity. A FEA-optimized ferrite motor with long linear excursion delivers deep bass response for the enclosure size. The low-profile single-driver design integrates into flown arrays with matching I SERIES full-range models via aligned suspension points and matched face widths. The weather-resistant PolyGlas enclosure is built for outdoor installation.
