In a development which will be of interest to larger live productions and festivals, the 110° horizontal dispersion LR28/110 is designed as an extension of the existing three-way, 80°dispersion LR28/80. Featuring the same faceprint downfill and components (two 14” woofers, four 6.5” midrange and a RBN1402rsr pro-ribbon driver) on a 110º waveguide, the LR28/110 is powered and controlled by four channels of the Sentinel10 amplified loudspeaker controller. Like the LR28/80, it has a rigging system that enables angle-setting on the cabinets without lifting the array, resulting in safer and faster set-up with minimal handling.

The LR28/110 is a 3-way, “larger-format” line-source sound system, to be used as vertical array, in medium to large applications with extended horizontal coverage.

The LR28/110 combines the highest sound quality possible with very high SPL capabilities and throw. It offers a fully predictable linear response behavior, with perfect intelligibility and identical tonal balance at any SPL. By implementing Alcons’ pro-ribbon technology for mid and high frequencies, a super-fast impulse response with up-to-90% less distortion under lowest power-compression is achieved.

The all-natural cylindrical wavefront of the multiple-patented, purpose-designed RBN1404rsr pro-ribbon transducer enables a precise pattern control, without any distortion-inducing horn constructions. The patented 110-degree horizontal dispersion is maintained up to the highest frequencies; The HF peak power handling of 3000W and RMS-to-peak ratio of 1:15, caters for a superb intelligibility and throw with maximum dynamic headroom reserve.

The MF-section features 4 high-efficiency 6.5” midrange transducers with Neodymium motor-structure in a slot-loaded configuration. The mid section and RBN high section are jointly mounted in/on the aluminium cassette for optimized heat-dissipation/reduced power-compression and prolonged system output.

The LF section consist of 2 reflex-loaded, custom 14” woofers with reinforced cone and large voice-coil Neodymium motor-structure for improved heat dissipation to reduce power compression.

The LR28/110 is powered and controlled by 4 channels of the Sentinel10 amplified loudspeaker controller; Through the integrated processing and feedback, the ALC offers LR28-specific drive processing with array-compensation, filter-presets, system eq, phase-matching, a.o.

The Signal Integrity Sensing™ pre-wiring of the LF and MF sections ensures dynamic cable/connector compensation between the LR28/110 and Sentinel, resulting in a fast and tight mid and bass response, while reducing distortion even further (system damping factor 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. The flying system supports different ways of array assembling and has a WLL of 24 cabinets under 10:1 safety.
