Turbosound NuQ118b 18″ Band Pass Subwoofer


18″ Band Pass Subwoofer for Portable PA and Installation Applications

The 2,400 Watt NuQ118B is an 18″ dual ported bandpass enclosure that is optimally tuned for extended low frequency response. Engineered to work in conjunction with TURBOSOUND loudspeaker management systems, the NuQ118B provides very high output FOH performance and is ideally suited for a wide range of music and live sound reinforcement applications.

The NuQ118B features a powerful, double suspension 18″ low frequency driver that utilizes a specialised inside/outside wound voice coil for higher magnetic density, better heat dissipation, high power handling capacity, and improved efficiency. For its size and operating bandwidth, the NuQ118B delivers extremely high output that is virtually distortion free – even in the most demanding applications.

A high quality semi-matt black paint makes the Turbosound NuQ118b a highly durable loudspeaker. Made from 18 mm birch plywood, the speaker box includes multiple threaded rigging points. Also included is a 35 mm pole socket along with carry handles for easy transport. High impact, locking corners for more stable ground stacking. The rear panel connector plate carries Neutrik speakon NL4 connectors, with input and link connections to allow standalone sub woofer usage, or sub woofer and satellite speaker linking via 4 core speaker cabling.
