One Systems 118/HSB 18" Direct Weather Subwoofer

Support Documentation:

The 118/HSB is an all-weather loudspeaker made of a lightweight copolymer. The 118/HSB may be used in direct weather outdoor installations, as well as indoor applications where extended low frequency response is required. The 118/HSB is a compact design that features a One Systems 18I/O 18-inch (457mm) extended bass transducer. The 118/HSB is available in both black and white color options.

The 118/HSB is optimized for outdoor applications such as theme parks, parade routes, football and baseball stadiums, as well as other entertainment and sports venues where permanent installation and extended low frequency response are required. The high acoustic output to size ratio makes the system ideal for pole mounted and wall mounted applications. The 118/HSB is also well suited for outdoor general public address applications. The system is equally suited for general purpose indoor applications in multipurpose rooms, indoor sports venues, and vocal intensive applications.

The 118/HSB utilizes 316-grade stainless steel (marine-grade) for all structural and rigging points. All associated One Systems rigging accessories are also 316-grade stainless steel. All metal components that are not structural feature a newly developed marine-grade powder coat over 304-grade stainless steel. This allows the 118/HSB to be used in oceanfront and cruise ship applications, as well as in general direct weather installations
