Following early previews at the Prolight+Sound Frankfurt and InfoComm USA in 2018, Alcons Audio has now shipped the Alcons Audio LR18B.
The Alcons Audio LR18B is the dedicated low-frequency extension to the Alcons Audio LR18 compact, mid-sized, pro-ribbon line-array system. It can also be combined with any other Alcons pro-ribbon system, Subwoofer in both permanent and portable applications. The front-loaded system delivers an accurate bass and sub response with the highest output under the lowest distortion. The Max-Vent port design combines further increased outputs with low power compression.
The LR18B is designed for optimal deployment flexibility because it can be used as a single subwoofer or in multiples – end-fire or cardioid array- together with Alcons Audio LR18 or in separate sub-only arrays. All functionality is possible in stacked or flown configurations.
The integrated stand mount adapter provides for easy top or sub-combinations with any Alcons pro-ribbon system. Adding to the flexibility, the versatile rigging system, rated for a high Working Load Limit with 10:1 safety ratio, enables front and rear array splaying and straight or pre-curved flown, cardioid arrays, to be flown beside or behind an Alcons Audio LR18 array. Array configurations can be simulated through the Alcons Audio LR18 GLL in the Alcons Ribbon Calculator (ARC), Alcons’ high-resolution 3D simulation program.
For full system performance, the Alcons Audio LR18B is to be driven and controlled by the ALC Sentinel amplified loudspeaker controller; Driven by the ALC, the Alcons Audio LR18B delivers full operation flexibility, maximum sound quality and output power with long-term operational reliability. The Signal Integrity Sensing pre-wiring ensures complete cable and connector compensation between the Alcons Audio LR18B and ALC, significantly increasing response accuracy and reducing both linear and non-linear distortion to an absolute minimum, regardless of cable length and system impedance.
Dr Philip de Haan, Head of Alcons R&D said, “with LR18B we are continuing our philosophy of bringing advanced transducer technology in our designs. The 18-inch is a new-generation transducer, fitted with a large, dual- 4.5-inch voice-coil Neodymium motor; this enables a significantly-extended excursion, thus SPL output, while maintaining a high sensitivity.”
Dr Hann continues: “Specific attention in this design has been paid to obtain lowest possible distortion; in combination with the SIS sensing circuit onboard the Sentinel, this combination of advanced technologies is a perfect match with our pro-ribbon mid-high systems.”
