108IM Light-Weight Copolymer-Based All-Weather Loudspeaker System

108IM Light-Weight Copolymer-Based All-Weather Loudspeaker System

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

The 118IM-sub system offers a complete selection of array and flying/suspension hardware.

The 118IM-Sub is optimized for outdoor applications such as theme parks, parade routes, football and baseball stadiums, and other entertainment/sports venues where permanent installation and extended low-frequency response is required. The high acoustic output to size ratio makes the system ideal for pole mounted and wall mounted applications. The system 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 general performance or vocal intensive applications.

The 118IM-Sub enclosure is made of medium-density polyethylene that is optimized for high UV exposure and long life in harsh environments. All internal and external rigging and suspension hardware, as well as the metal grille are stainless steel or high strength aluminum. All suspension points are made with 304-grade stainless steel.

The grille is a 3-layer "rain shield" design that will minimize direct rain contact with the system's transducers. The unique vent design also allows for easy moisture drainage from the interior of the enclosure. The enclosure and grille design are rated to IEC 529 IP45 (solid object penetration to 1 mm (0.04 inches) and water jets from any direction). The enclosures and components are also rated to Mil Spec 810.

The input section consists of a 5-pin barrier strip. A weather cover is provided with an integral gland nut connector for outdoor applications. The gland nut is weather proof and is rated NEMA 6P (IP68). The connector will accommodate cable outside diameters from 7mm to 12mm (0.236" to 0.472"). The maximum diameter will accommodate most 2 conductor AWG 12 cable assemblies.

Because the ONE SYSTEMS 118IM-Sub is designed for permanent installation applications a variety of rigging and suspension options are available. The 118IM-Sub has multiple M10 mounting points. An M10 forged shoulder eye bolt kit is available for all M10 suspension points.

The 118IM-Sub may be mounted in selected installations (when permitted by local codes and appropriate substrates) using either a ONE SYSTEMS pan and tilt bracket (PT-76a) or the Pole Mount System EX-3. The 118IM-U U-bracket is also an available option.
