ONE SYSTEMS 218Sub-W ลำโพง Dual 18" Subwoofer 1600 watts

 

The 218Sub-W™ is a double 18 inch high output low frequency sub woofer 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 where substantial low frequency energy is specified.

The 218Sub-W may be used in outdoor installations as well as indoor applications where high output and accuracy are required. The unique design of the 18 inch 18I/O woofer provides an excellent combination of high sound pressure levels and low distortion The ONE SYSTEMS® 218SubW features an 18mm birch 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 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 low frequency design is patent pending. The 18 inch 18I/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 218Sub-W is designed for permanent installation applications a variety of rigging and suspension options are available. The 118SubW has 22 M10 mounting points. An M10 forged shoulder eye bolt kit is available for all M10 suspension points
