Following early previews at this year’s Prolight + Sound Frankfurt and InfoComm USA, Alcons Audio is now shipping the LR18B.
The LR18B is the dedicated low-frequency extension to the LR18 compact mid-sized pro-ribbon line array system. It can also be combined with any other Alcons pro-ribbon system, as subwoofer in both permanent and portable applications.
The front-loaded system delivers a accurate bass and sub response with high output under low distortion. The Max-Vent port design combines further increased output with low power compression.
The LR18B is designed for optimal deployment flexibility, as it can be used as single subwoofer or in multiples; As end-fire or cardioid array; Together with 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/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 besides or behind an LR18 array.
Array configurations can be simulated through the LR18 GLL in the Alcons Ribbon Calculator (ARC), Alcons’ 3D simulation program.
For full system performance, the LR18B is to be driven and controlled by the ALC Sentinel amplified loudspeaker controller; Driven by the ALC, the LR18B delivers full operation flexibility, maximum sound quality and output power with long-term operation reliability.
The Signal Integrity Sensing pre-wiring ensures complete cable/connector compensation between the 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.
Philip “Dr. Phil” de Haan, head of Alcons R&D says, “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.”
de Haan 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.”
