Modular Morphing RR12

Based on Alcons’ R-Ray design study from 2008, the RR12 extends Alcons’ famous line-source technology into different applications. By implementing the unique features of Alcons’ multiple-patented pro-ribbon technology in a modular concept, the RR12 has been developed as “building block” to create tight packed arrays for controlled sound coverage in the widest variety of audience areas.

Due to the pro-ribbon’s all-natural cylindrical wavefront, no (distortion-increasing) adapters are needed to obtain perfect coupling for super precise directivity up to even the highest frequencies (to beyond 20kHz.).

The system features the purpose-designed Alcons-proprietary RBN602rsr 6″ pro-ribbon driver and a custom-designed 12″ woofer with 4″ voice coil, dual-spider suspension with forced-venting; while both transducers have Neodymium motor structures, the RR12 has a very high performance-to-weight ratio.

The purpose-designed 6″ pro-ribbon driver is based on Alcons’ all-new “RBN02” pro-ribbon platform; This platform (as also featured in Alcons’ LR24 flagship line-array) dramatically raises the bar in power handling and efficiency of pro-ribbon transducer technology.

The RBN602rsr is coupled to an asymmetric “Morph-Max™” wave-guide, designed using the latest, state-of-the-art development tools: Proprietary-programmed analysis/simulation software in combination with 3D-prototyping and special manufacturing techniques, resulted in this non-compressing, resonance-free multi-cell guide with wide-band razor-sharp directivity control up to beyond 20kHz.

The trapezoidal cabinet is fitted with integrated mounting hardware, enabling array assembly with just a single operation from the rear of the cabinet.

Tight-packing the RR12 in horizontal or vertical arrays for stacked or flown applications, dispersion patterns are formable in 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 has to be driven by the Sentinel amplified loudspeaker controllers; The system’s response is optimised by factory presets, selectable for each array configuration; Also presets are available for phase-matching low-frequency extensions.

The SignalIntegritySensing™ pre-wiring ensures complete cable/connector compensation between the RR12 and Sentinel, resulting in a fast and tight mid and bass response, while reducing distortion even further.

Utmost reliability is one of the main essentials for Alcons systems: Each transducer/processing design has to pass a rigorous 1000 hour test at maximum (clip) levels. This is a key element in Alcons’ system development.

Each array configuration can be simulated in the Alcons Ribbon Calculator (ARC), Alcons’ high-resolution 3D simulation program.
