The TURBOSOUND DUBLIN TCX115B is a 4,000 Watt bandpass subwoofer designed to complement TCX series mid/high cabinets in a wide range of installed and portable music sound reinforcement applications. It consists of a double suspension 15" low frequency driver with inside/outside wound coil in a low distortion dual port bandpass enclosure designed for maximum sound pressure level and extended low frequency response.

Constructed from 3/4" (18 mm) birch plywood, the cabinet is available in hard wearing semi matt black paint or optional white textured paint, and includes internal M10 threaded rigging points that allow it to be suspended in permanent installations using M10 eyebolts. A pole mount socket is provided to allow two-way cabinets to be mounted at the correct height above the subwoofer. The rear connector panel provides two Neutrik speakON* NL4 connectors for input and link functions, wired in parallel with a 4-way barrier strip connector.

A weather resistant version is available rated to IP54 comprising moisture treated woodwork, weatherised components, plated and outdoor powder coated grille with reticulated foam backing, stainless steel fixings, and a captive cable tail secured through a sealed cable gland on an aluminium panel. Additionally, external handles and the pole mount socket are omitted in order to provide a sealed enclosure and prevent the ingress of water or moisture.
