PL+S 2016: Alcons Audio debuts LR18 line array

Alcons Audio will debut its LR18 pro-ribbon line-array at the Prolight + Sound tradeshow  in Frankfurt next week.

The three-way compact mid-size format line source sound system implements Alcon’s pro-ribbon technology for mid and high frequencies, enabling the LR18 to offer a ‘fully intuitive’ linear response with non-compressed identical tonal balance at any SPL.

The all-natural cylindrical wavefront of the RBN702rs 7in pro-ribbon transducer and the acoustically and electronically symmetrical component configuration are designed to bring significant pattern control to both the vertical and horizontal plane, without any distortion-inducing horn constructions.

The MF-section features a 6.5in midrange transducer with neodymium motor-structure co-axially mounted behind the RBN702rsr pro-ribbon driver. The LF section consists of two extended-excursion, reflex-loaded 8in woofers with oversized 3in voice-coil neodymium motor-structure.

The form-factor matching LB18 will also receive its official launch, consisting of two of the same 8in LF transducers. Adding LB18 modules enlarges the array length, extending the controlled projection of the LR18 down to the lower frequencies, while increasing throw of the low-mid frequencies over distance.

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 (32 units for the LB18).

Array configurations can be simulated in the new release of Alcons’ Ribbon Calculator (ARC3)- the company’s high-resolution 3D simulation program.

Philip “Dr. Phil” de Haan, Alcons’ head of R&D, comments: “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.”

“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,” added Tom Back, Alcons’ managing director.

“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.”
