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 1500W and RMS-to-peak ratio of 1:15, caters for a superb intelligibility and throw with maximum dynamic headroom reserve.
Philip 'Dr. Phil' de Haan, Alcons' head of R&D comments, "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, adds, "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. 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!".
