Medium Power 18-inch Subwoofer

I SERIES Subwoofer 600 weather-resistant loudspeakers provide excellent 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 IS6-118WR is a compact, direct radiating 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 capabilities provides deep bass response for the enclosure’s diminutive size.
