Alcons Introduces LR16B Line-Array Bass System

The Netherlands (June 15, 2004)--As an addition to its L-series of products, Alcons has introduced the LR16Bass, a high-output bass-system, for both permanent and portable applications. It is designed as a low-frequency extension to the LR16 line-array speaker module, in both flown and stacked configuration and has one of the highest "efficiency-to-weight/size ratios" in the industry.

The Netherlands (June 15, 2004)--As an addition to its L-series of products, Alcons has introduced the LR16Bass, a high-output bass-system, for both permanent and portable applications. It is designed as a low-frequency extension to the LR16 line-array speaker module, in both flown and stacked configuration and has one of the highest "efficiency-to-weight/size ratios" in the industry.

The main focus with the development of the LR16B was to get the highest efficiency possible, within the weight/size parameters set by the line-array application. A flown application means the system is placed in "full-space" conditions, which brings a substantial reduction (-3dB) of output, versus a "half-space" stacked application. In order to achieve a higher efficiency than the conventional front-loading arrangement, the long-excursion 15" drivers are double-vented, double-tuned in a band-pass loading configuration.

The resulting true 102dB efficiency, in combination with the 3200W power handling, brings a 137dB peak SPL from a very compact cabinet. As the LR16B is primarily designed to be used in flown applications, special attention has also been paid to the weight of the system; the cabinet is made of 15mm/0.6in Birch wood with very clever bracing for a lightweight yet rigid construction. The drivers are two long-excursion 15" woofers with Neodymium magnet structures and low power-compression design.

The integrated "heavy-duty" flying system, also featured in the LR16, doesn't have any separate/loose parts and is certified to an unusual high safety-rating--500kg/1.000lb single-point, safety ratio 10:1. In stacked configuration, the two-side usable flying hardware of the LR16B forms a stable foundation for LR16 arrays. The LR16B is included in the latest version of Alcons Ribbon Calculator (ARC) prediction software.
