LATEST RIBBON ARRAY
By Graeme Hague
14 January 2014
Alcons’ new RR12 cabinet is designed to implement the features of Alcons’ multiple-patented pro-ribbon technology into a modular concept, meaning the RR12 has been developed as a “building block” to create tight packed arrays for controlled sound coverage. The system uses Alcon’s proprietary RBN602rsr 6-inch pro-ribbon driver and a custom-designed 12-inch woofer with 4-inch voice coil, and a dual-spider suspension with forced-venting. While both transducers have Neodymium motor structures, the RR12 has a very high performance-to-weight ratio. Due to the pro-ribbon’s cylindrical wave-front, no adapters or converters are needed to obtain coupling for precise lobe-free directivity up to even the highest frequencies (to beyond 20kHz.). The purpose-designed 6-inch pro-ribbon driver promises 1000W peak power handling and a 1:17 dynamic RMS-to-peak ratio. The trapezoidal cabinet is fitted with integrated mounting hardware, enabling focus increments of 30-degrees, 30, 60, 90, 120 degrees in the coupling plane, by asymmetric 60-degrees (+20/-40deg) in the non-coupling plane. The RR12 is driven by the Sentinel 4-channel amplified loudspeaker controllers. The system’s response is optimised by factory presets, selectable for each array configuration. Presets are also available for phase-matching low-frequency extensions. Full specs are at www.alconsaudio.com
