Alcons’ LR24 3-way, “larger-format” line-source sound system, to be used as vertical array, either in stacked or flown configuration, promises to handle even the largest sound reinforcement applications.
More details from Alcons (www.alconsaudio.com):
The LR24 is redefining sound reinforcement, as it combines a HiFi-grade sound quality with very high SPL capabilities. Loaded with Alcons’ proprietary pro-ribbon technology for mid and high frequencies, the LR24 offers very fast impulse response with full-dynamics, up-to-90% less distortion under lowest power-compression. The all-natural (Isophasic) cylindrical wavefront of the pro-ribbon HF transducer enables a precise pattern control, without any distortion-inducing horn constructions.
Philip “Dr. Phil” de Haan, head of Alcons R&D and initiator of multiple patents: “Until now, this extraordinary high level of precision in sound quality was not obtainable in sound reinforcement, especially not at these sound pressure levels. With the new RBN02 pro-ribbon transducer platform, the HF output capabilities lie above that of the largest line-array system”.
De Haan continues: “The design objective was to create a system with an absolutely neutral, 1:1 non-coloring and predictable linear response behaviour at any sound pressure level, with highest projection accuracy. Thanks to our 25+ years experience in pro-ribbon transducer technology, DSP electronics and acoustics we were able to realize our goal: What you mix is what you get!.”
The HF section features the RBN1402rsr pro-ribbon driver with 14-in. voice-coil. The combination of the high sensitivity + the unusually high HF peak power handling of 3000W caters for a unique intelligibility and throw with ample dynamic headroom reserve under any condition. The purpose-designed Alcons RBN1402rsr driver features no less than 4 patents.
The MF-section features 4 high-efficiency Neodymium 6.5” midrange transducers in a symmetrical loaded configuration; The MF section is made out of aluminium and forms an integral part with the HF section, for optimized heat management, maintaining high-output over a longer period of time.
The LF section consist of 2 long-excursion, reflex-loaded 12” woofers with carbon-reinforced cones. The Neodymium motor-structure features a 4” voice-coil and dual-spider suspension with forced-venting, again for improved heat dissipation and reduced power compression.
The SignalIntegritySensing pre-wiring of the LF and MF sections ensures a fully dynamic cable/connector compensation between the LR24 and Sentinel, resulting in a fast and tight mid and bass response, regardless of impedance or cable length, while reducing distortion even further (system damping factor >10.000).
The LR24 has a linear frequency response from 51Hz to 20.000Hz (-3dB), where the low-end control can be extended by the LB24 double-12” bass array-extension with the same cabinet foot print. The horizontal dispersion of 80-degrees is maintained down to 190Hz. The vertical dispersion enables a maximum cabinet splay angle of 6-degrees, still maintaining complete wavefront coherency without any disruption or lobing up to 20.000Hz.
The system is to be exclusively driven by 4 channels of the Sentinel, Alcons’ proprietary 10kW amplified loudspeaker controller. Through the integrated (steering) processing and feedback, the ALC offers LR24-specific drive processing with optimal response, directivity, reliability and user-friendliness.
Utmost reliability is one of the main essentials for Alcons systems: Each transducer design has to pass a rigorous 1000 hour test at maximum (clip) levels. This is a key element in Alcons’ transducer design.
The rigging system enables angle-setting on the cabinets, without lifting the array: This results in faster set-up times with minimal handling. The flying system supports different ways of array assembling, per single cabinet or 4-cabinet pre-rig and is certified for 24 cabinets in a 10:1 safety ratio.
The LR24 is element of a complete, application-configurable package, including the LB24 bass array- extension, BC543 triple 18” cardioid subwoofer system, Sentinel amplified loudspeaker controller, ARC 3D-simulation tool and system connection and transport logistics.
The LR24 is part of “The Ribbon Network” inventory, Alcons’ global dry-hire and partner network and comes with a 6-years “no hassle” warranty.
