DUBLIN TCX115B-WH

The DUBLIN TCX115B-WH is a 4,000 Watt 15" dual ported bandpass enclosure that is optimally tuned for extended low frequency response. Engineered to work in conjunction with TURBOSOUND loudspeaker management systems, the TCX115B-WH provides very high output FOH performance and is ideally suited for a wide range of music and live sound reinforcement applications.

Custom-Engineered DriversTurbosound is recognised the world over for designing and building some of the most iconic loudspeakers and subwoofers. We take meticulous care and pride in maintaining that reputation by utilising only drivers designed specifically for each application – it’s what sets us apart from the competition.The TCX115B-WH features a powerful, double suspension 15" low frequency driver that utilises a special 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 TCX115B-WH delivers extremely high and virtually distortionfree output for world-class low frequency performance that will stand the test of time.

Bandpass Enclosure DesignBandpass enclosures are extremely efficient, creating maximum bass output within a specific frequency range by increasing the acoustic load presented to the driver. The low distortion bandpass design utilised in the TCX115B-WH reinforces the bass musical instrument frequencies, and steep cut-off slopes ensure an effective acoustic transition for use with DUBLIN Series full-range loudspeakers. A typical application could consist of an TCX115B-WH providing the low-frequency bass extension for one, or two DUBLIN Series top cabinets.

Construction and Connectivity

Constructed from 15 mm (5⁄8") birch plywood, the cabinet is finished in hard wearing semi matt 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 industry-standard twist-lock speaker connectors for input and link functions, wired in parallel with a 4-way barrier strip connector.

Rock-Solid PerformancePrimarily designed for permanent installations such as houses of worship, banquet facilities, night clubs – and a host of other venues, the 4,000-Watt DUBLIN TCX115B-WH puts touring-grade sound quality into a scalable loudspeaker system. In portable applications the subwoofer can be used with speaker poles – plus carrying handles are provided for ease of installation and transportation.
