One Systems, based in Nashville, announced the debut of the all-weather 118IM-Sub at Prolight + Sound Stand G.40.D in Hall 8.0. The announcement was made by One Systems President Doug MacCallum, and the company states that the 118IM-Sub will be available in early May 2014.
The 118IM-Sub is built using the One Systems 18I/O 18-inch (457mm) extended bass transducer featuring its patented Inside/Only (I/O) voice coil design. The medium-density polyethylene enclosure is optimized for high UV exposure and harsh environments.
Measuring 23×20.1×20.7 inches, it has a stated frequency response (+3 dB) of 40 to 120 Hz and a coverage pattern that is said to be nearly 100-percent omnidirectional. It is also designed to be pole mounted for easy use in stadiums and amusement parks in conjunction with One Systems’ full-range weatherproof speakers.
All external rigging and suspension hardware, as well as the metal grille, are built using 304-grade stainless steel. The structural internal rigging is made with high-strength aluminum. The grille is a 3-layer “rain shield” design minimizes direct rain contact with the system’s transducers. Its vent design also allows for easy moisture drainage from the interior of the enclosure.
The 118IM-Sub is designed to IEC 529 IP45, solid object penetration to 1 mm (0.04 inches) and water jets from any direction. The enclosure and components are also designed to Mil Spec 810.
The input section comprises 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 7 mm to 12 mm (0.236 inches to 0.472 inches). The maximum diameter will accommodate most 2-conductor AWG 12 cable assemblies.
