Description
PRAGUE TPZ153/64
The 3-way full range TPZ153/64 is a switchable bi-amp/tri-amp 15″ 3,400 Watt arrayable loudspeaker system that is ideally suited for a wide range of speech and music sound reinforcement applications. The TPZ153/64 is designed to work in conjunction with TURBOSOUND loudspeaker management systems, providing optimal FOH performance, as well as offering considerable flexibility to readily adapt to varying venue requirements.
The TPZ153/64 arrayable loudspeaker features a carbon fibre loaded 15″ low frequency driver with an inside/outside wound low mass voice coil for improved transient response, a carbon fibre loaded 8″ high sensitivity mid range driver, and a titanium dome 1.4″ neodymium motor high frequency compression driver mounted on a rotatable 60° horizontal by 40° vertical waveguide. The mid range and high frequency drivers are matched with an internal passive crossover network in a reflex-loaded enclosure, and bi-amp or tri-amp mode can be enabled by means of a rear panel switch.
Finished in a highly durable semi matt black paint, the cabinet is constructed from 15 mm (5⁄8″) birch plywood – and includes a rugged powder coated perforated steel mesh grille backed with reticulated foam. Internal M10 threaded rigging points are provided for suspension in any orientation, or mounting with dedicated brackets – available separately. The TPZ153-FK fly kit is also available for suspension of three TPZ153 enclosures with array angles ranging from 50 – 90° in 5° increments. The rear panel connector plate carries Neutrik speakON* NL4 and barrier strip connectors for input and link connections to additional enclosures.
