Biamp Community IS8-118 High Power 18-Inch Subwoofer (Black) - 911.1151.900

The Community IS8-118 is an I Series Subwoofer 800 18" 1600W (8 Ohms) passive installation loudspeaker. This subwoofer is well-suited for applications such as houses of worship, auditoriums, restaurants, meeting rooms, corporate A/V systems, arenas, stadiums, or any application where extended low-frequency reinforcement 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.

The compact, low-profile single driver I Series subwoofers are ideal for distributed or concealed sub-bass and are the perfect choice for ground stack applications. Additionally, each cabinet was carefully designed to provide matching face widths and suspension point locations for seamless integration into flown arrays with I Series full-range models when additional LF extension is needed but a compact appearance is required. 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 IS8-118 is a compact, 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. FEA optimized linear suspensions and high flux neodymium motors with long linear excursion capabilities provide exceptionally deep bass for the enclosure’s diminutive size.
