Alcons Audio Introduces the LR18 Pro-Ribbon Line Array at Frankfurt Prolight +SoundThe Prolight + Sound show in Frankfurt will see the official debut of the Alcons Audio LR18 pro-ribbon line-array, the three-way, "compact-mid-size" format line-source sound system, combining the highest sound quality with very high SPL capabilities and throw. Alcons will exhibit in Hall 3.1, stand B50. By implementing Alcons' multiple-patented pro-ribbon technology for mid and high frequencies, a super-fast impulse response with up-to-90% less distortion is achieved. This enables the LR18 to offer a fully intuitive linear response, with very high intelligibility and non-compressed identical tonal balance at any SPL. The all-natural cylindrical wavefront of the purpose-designed RBN702rs 7" pro-ribbon transducer and the acoustically and electronically symmetrical component configuration bring a remarkable pattern control in both the vertical as well as the horizontal plane, without any distortion-inducing horn constructions. The pro-ribbon's power handling of 1,500W and RMS-to-peak ratio of 1:15, caters for a superb intelligibility and throw with maximum dynamic headroom reserve. The MF-section features a high-efficiency 6.5" midrange transducer with neodymium motor-structure co-axially mounted behind the RBN702rsr pro-ribbon driver. The LF section consist of two extended-excursion, reflex-loaded 8" woofers with oversized 3" voice-coil neodymium motor-structure; Due to the extraordinary design, this 8" surpasses the output of even larger drivers in higher-category line-array systems, while maintaining the unobtrusive face print of a compact system. The LR18 is driven by two channels of the Sentinel amplified loudspeaker controller, optimizing the system's response by LR18-specific drive processing and feedback for each array configuration, including presets for phase-matched low-frequency extensions. A form-factor matching LB18 is also available, consisting of two of the same 8" LF transducers; Adding LB18 modules enlarges the array length, extending the controlled (cylindrical) projection of the LR18 down to the lower frequencies, while increasing throw of the low-mid frequencies over distance. The signal integrity sensing pre-wiring ensures dynamic cable/connector compensation between the LR18 (/ LB18) and ALC, without any preset requirement. This offers a 1:1, undistorted natural sound reproduction, regardless of cable length and amplifier impedance load (system damping factor at the speaker terminals of 10,000). The rigging system enables angle-setting on the cabinets without lifting the array, resulting in safer and faster set-up with minimal handling and a WLL of 24 cabinets under 10:1 safety (LB18 32 units). Array configurations can be simulated in the new release of Alcons Ribbon Calculator (ARC3), Alcons' high-resolution 3D simulation program. Philip "Dr. Phil" de Haan, Alcons' head of R&D: "with the development of the LR18, we followed the design footsteps and system approach of the LR28, Alcons' large format line-array and the LR18's larger brother. We paid specific attention to the projection of the LR18. In the vertical (coupling) plane, the side-lobe free projection creates a perfect wavefront for an unprecedented throw. In the horizontal plane, the category-leading 90-degree horizontal dispersion is completely maintained from 20kHz down to 360Hz for a seamless coverage." Tom Back, Alcons' managing director: "This is one of the most important product releases for Alcons Audio to date: Not only for the market volume in both the install and rental market, but also to complete the LR28 large-format touring system package." Back continues: "When we started development of the LR18, we knew we had to pull out all stops to make this a benchmark system. Not only in the projection control, but also in the 1:1 sound reproduction in any type of application, from classical up to rock 'n roll. The result is: What You Mix Is What You Get!" The LR18 is part of The Ribbon Network, comes with a six-year "hassle-free" limited warranty and is available for ordering from today. Off-site demonstrations will take place during the Prolight + Sound show on Wednesday, April 6, and Thursday, April 7, of the show. ![](/std_images/blank.gif)
