The LR24 is a 3-way, “larger-format” line-source sound system, to be used as vertical array, either in stacked or flown configuration, for even the largest sound reinforcement applications. The LR24 offers HiFi-grade sound quality for high-SPL capabilities. Loaded with Alcons’ proprietary pro-ribbon technology for mid and high frequencies, the LR24 provides fast impulse response with full-dynamics and 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.”
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 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 dual 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 LR24 has a linear frequency response from 51 Hz to 20 kHz (-3dB), where the low-end control can be extended by the LB24 double-12” bass array-extension with the same cabinet footprint.
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.
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.
