115RW 15” TWO-WAY HIGH OUTPUT SOUND REINFORCEMENT SYSTEM

The 115RW™ is a 15” two way high output sound reinforcement system. The system utilizes a rectangular enclosure geometry. This geometry provides increased low frequency response due to its larger internal volume, as compared to a conventional trapezoidal enclosure. This design is intended for applications when maximum low frequency output is required but the enclosure will be “single hung”. (The 115TW is optimized for array applications due to its trapezoidal geometry).

For additional information see the www.ONESYSTEMS.com web site for a discussion regarding the advantages of rectangular enclosures versus trapezoidal geometries.

The 115RW may be used for either single hang installations or for general portable applications.

The 115RW may be used in outdoor installations as well as indoor applications where high intelligibility and accuracy are required. Like all ONE SYSTEMS® products, the 115RW was designed to not only offer excellent full range fidelity but superior vocal reproduction and intelligibility as well. The system consists of a single 15 inch 15I/O woofer and an ET driver on a fully rotatable high frequency horn.

The ONE SYSTEMS 115RW features an 18mm birch rectangular plywood enclosure that utilizes stainless steel internal structural supports to enable a variety of suspension points.

The grill is a 3 layer “rain shield” design that will minimize direct rain contact with the systems transducers. All internal and external metal hardware, as well as the grill, are stainless steel. 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 input is user switchable for either full range or bi amp operation. The switch is located on the input plate and is isolated from direct weather by the weather cover.

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 ET designs that offer extended bandwidth polar control and very low distortion. The ET-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 short throw and downfill applications. The second horn, the ET-60/40 is designed for medium to long throw applications. It offers a 60 degree horizontal by 40 degree vertical radiation pattern and is also fully rotatable.

Although the 115RW is shipped with the ET- 60/40 horn installed the ET-105/60 is also included. A simple internal jumper optimizes the crossover for either high frequency horn. (For details related to changing high frequency horns see the “HOW TO” section in the ONE SYSTEMS web site, www.ONESYSTEMS.com)

The patent pending ET driver (full details are available at the ONE SYSTEMS web site, www.ONESYSTEMS.com) 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. This feature provides extended high frequency dispersion. The ET driver has a large format titanium diaphragm and a close spaced circumferential ring phase plug to insure extended high frequency bandwidth.

The low frequency design is also patent pending. The 15 inch 15I/O woofer (Inside Only) utilizes a unique voice coil wind on the inside of the voice coil support structure. This design allows for both high magnetic system displacement as well as increased thermal transfer. This results in reduced power compression and higher reliability.

Because the ONE SYSTEMS 115RW is designed for permanent installation applications (as well a portable use)a variety of rigging and suspension options are available. The 115RW has 20 M10 mounting points.

An M10 forged shoulder eye bolt kit is available for all M10 suspension points
