The 2,000 Watt NuQ115B is a front loaded 15" subwoofer system that is ideally suited for a wide range of music and live sound reinforcement applications. Engineered to work in conjunction with Turbosound loudspeaker management systems, the NuQ115B provides optimal FOH performance, as well as exceptional drum and side fill monitoring applications.

A bass reflex port design enclosure, the NuQ115B features a high power, double suspension 15" low frequency driver that utilizes a specialized inside/outside wound voice coil for higher magnetic density, better heat dissipation, high power handling capacity, and improved efficiency. The NuQ115B subwoofer provides fast and accurate transient response for virtually distortion-free operation.

Finished in a highly durable semi matt black paint, the cabinet is constructed from 18 mm (¾ ") birch plywood – and includes a rugged powder coated perforated steel mesh grille backed with reticulated foam. A 35 mm pole socket, internal M10 rigging points, and recessed carry handles are standard, as are the high impact interlocking corners, which also ensure ground stacking stability. The rear panel connector plate carries Neutrik speakON * NL4 connectors, with switchable input and link connections to accommodate standalone subwoofer applications, or subwoofer and satellite speaker connectivity via 4 core speaker cabling
