Alcons launches speaker for Digital Cinema immersive sound24 October 2014
The CRS12GT is a two-way passive-filtered loudspeaker, designed to meet all requirements of current and future Digital Cinema immersive surround sound formats. The first CRS12GTs have already been installed in larger Dolby Atmos installations throughout Europe.
Featuring Alcons’ proprietary multiple-patented pro-ribbon driver technology, the CRS12GT is said to combine an exceptional clarity and intelligibility with an unusually high dynamic range and up to 90% less distortion than traditional cinema surround systems. It is designed to reproduce complex sound sources as speech, music and effects to offer highly realistic immersive surround sound reproduction.
By using identical MHF pro-ribbon transducers for screen and surround systems, an exceptionally wide and uniform sound stage throughout the entire listening area is realised. This is especially striking in multi-channel cinema surround systems, but also in performing arts theatre surround systems.
The CRS12GT system consists of one RBN601 6in pro-ribbon driver for HF and a vented 12in mid-bass for LF reproduction. The CRS12GT HF section has a 1,000W peak power input, enabling a 1:15 RMS-to-peak dynamic range with lowest distortion from 1,000Hz to beyond 20,000Hz. The absence of a ‘compression threshold’ caters for a linear tonal balance at any SPL, from the almost silent whisper to even the largest explosions.
The patented horizontal dispersion of the Alcons RBN601 pro-ribbon transducer guarantees a very stable sound projection throughout the operating bandwidth, both on- and off-axis.
The all-neodymium speaker configuration lowers the total mounted system weight and facilitates easier installation.
Developed as high-output surround speaker in immersive surround systems, the CRS12GT is available with a 90° horizontal x 40° vertical dispersion (CRS12GT90) and with 60° horizontal x 30° vertical dispersion (CRS12GT60), for the surround locations closest to the screen channels. In combination with the 10° slanted baffle, the multi-faceted trapezoidal cabinet shape and the upside-down speaker arrangement, this enables a very precise projection on the critical listening area, while preventing wall and ceiling reflections.
For full system performance, the CRS12GT can be driven by an Alcons ALC amplified loudspeaker controller, delivering maximum high-end hi-fi sound quality with increased headroom and utmost operational reliability. The CRS12GT is available in 8-ohm and 4-ohm versions, for maximum amplifier efficiency in individually amplified immersive surround systems.
A specific Alcons feature, most interesting for cinema applications with its long speaker cables, is the Signal Integrity Sensing pre-wiring. This circuit inside the ALC ensures complete cable/connector compensation between the CRS12GT speaker and ALC amplified loudspeaker controller, significantly increasing response accuracy, regardless of cable length and system impedance, with tight and accurate mid and bass response as result (system damping factor of 10,000).
The CRS12GT can be supplied in any RAL colour for perfect interior blending and comes with a six-year ‘no-hassle’ warranty.
