Alcons Audio has announced the LR28 larger format pro-ribbon line array for the concert touring and large-scale installation market at Prolight + Sound in Frankfurt.
Based on last year’s presented LR24 line-array, the LR28 promises an increase in HF and LF output over its predecessor, combining ‘HiFi-grade sound quality with highest SPL capabilities’. Featuring Alcons’ proprietary pro-ribbon technology for mid and high frequencies, the LR28 offers ‘very fast impulse response with full-dynamics, up-to-90% less distortion under lowest power-compression’.
The LR28 also features the proprietary RBN1404rsr 14in pro-ribbon driver, quad slot-loaded 6.5in mid-range transducers and double, purpose-customised 14in woofers, while the all-natural (Isophasic) cylindrical wavefront of the pro-ribbon HF transducer enables pattern control, without any distortion-inducing horn constructions.
The LR28 is element of a complete, application-configurable package, including the LB28 bass array- extension, BC543 triple 18in cardioid subwoofer system, Sentinel amplified loudspeaker controller with ALControl remote-control application, ARC 3D-simulation tool and system connection and transport logistics.
“Until now, this extraordinary high level of precision in sound quality was not obtainable in sound reinforcement, especially not at these sound pressure levels,” commented Philip de Haan, head of Alcons R&D and initiator of multiple pro-ribbon transducer patents. “Over the last year, we were able to substantially increase the output capabilities of the then-new RBN02 pro-ribbon transducer platform, which high frequency output was already above that of the largest systems; This resulted in the development of the 04 pro-ribbon platform.”
“The design objective was to create a system with an absolutely neutral, non-colouring and predictable linear response behaviour at any sound pressure level,” De Haan continued. “Thanks to our 30 years experience in pro-ribbon transducer technology, DSP electronics and acoustics we were able to realise our goal: What you mix is what you get!”
