The 108IM™ is a light weight copolymer based all weather loudspeaker system. The 108IM may be used in direct weather outdoor installations as well as indoor applications where high vocal intelligibility and accuracy are required. Like all ONE SYSTEMS® products, the 108IM was designed to not only offer excellent full range fidelity but superior vocal reproduction and intelligibility as well. The system consists of a single 8” woofer and ETS driver coupled to a fully rotatable high frequency horn.

The 108IM system offers a complete selection of array and flying/suspension hardware. The enclosure is also available with a 75 watt 3 tap line matching transformer.

The 108IM transformer version may be ordered with either a 100V or 70.7V primary.

The 108IM is optimized for outdoor applications such as football stadiums, baseball stadiums, race tracks and other sports venues where permanent installation is required as well as a direct weather exposure. The high acoustic output to size ratio makes the system ideal for short throw (105x60) or defined coverage medium Q (60x40) 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 108IM enclosure is a copolymer optimized for high UV exposure and long life in harsh environments. All internal and external rigging and suspension hardware, as well as the metal grill are stainless steel or high strength aluminum.

The grill is a 3 layer “rain shield” design that will minimize direct rain contact with the systems transducers. The unique vent design also allows for easy moisture drainage from the interior of the enclosure.

The enclosure and grill 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 both 4 pin Neutrik Speakons as well as a stainless
steel hardware barrier strip. A weather cover is provided with an integral gland nut connector for outdoor applications. In the outdoor configuration connections are made thru the 4 position barrier strip.

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.

The basic design utilizes a patent pending high frequency driver the will accommodate a variety of high frequency radiation patterns. There are two fully rotatable high frequency horns available.

Both horns are ETS designs that offer extended bandwidth polar control and very low distortion. The ETS-105/60 is a 105 degree horizontal by 60 degree vertical pattern and may be rotated to also provide a 60 degree horizontal by 105 degree vertical for downfill applications. The second horn is the ETS-60/40. It offers a 60 degree horizontal by 40 degree vertical radiation pattern and is also fully rotatable.

Although the 108IM is shipped with the ETS-60/40 horn installed the ETS-105/60 is also included. A simple internal jumper optimizes the crossover for either high frequency horn.

The patent pending ETS driver is a unique “equivalent throat” design that allows the radiation pattern to be controlled by the phase plug summation plane rather then the conventional “exit diameter” at the end of the driver structure. The ETS driver has a titanium diaphragm and a close spaced circumferential ring phase plug to insure extended high frequency bandwidth.

Because the ONE SYSTEMS 108IM is designed for permanent installation
applications a variety of rigging and suspension options are available. The 108IM has multiple M8 mounting points.

An M8 forged shoulder eye bolt kit is available for all M8 suspension points. The 108IM may be mounted in selected installations (when permitted by local codes and appropriate substrates) using either a ONE SYSTEMS pan and tilt bracket (PT-35). Bracket or the 108IM-U.

The 108IM is also available in a line matching transformer version in both 100V and 70.7V ratings. The internal transformer is a 75 watt 3 tap (75 watts, 37.5 watts, and 18.75 watts). This is the 108IM-100 or 108IM-70 version.
