The DUBLIN TCX115B-R 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-R provides very high output FOH performance and is ideally suited for a wide range of music and live sound reinforcement applications.
TURBOSOUND 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-R 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-R delivers extremely high and virtually distortion-free output for world-class low frequency performance that will stand the test of time.
Bandpass Enclosure Design
Bandpass 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-R reinforces the bass musical instrument frequencies, and steep cutoff slopes ensure an effective acoustic transition for use with DUBLIN Series full-range loudspeakers. A typical application could consist of an TCX115B-R 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 black textured paint and includes internal M10 threaded rigging points for use in permanent installation. The rear panel features a sealed captive cable and gland for added protection from the elements.
Designed to Weather the Elements
When permanently installed, the TCX115B-R presents a discreet appearance with no visible side handles for visually unobtrusive loudspeaker arrays. The weatherised paint, zinc plated grill with outdoor powdercoat, and weather resistant coated drivers deliver an iP54 rated package that not only provides class-leading performance, but maintains its attractive appearance for many years.
