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 super accurate bass and sub response with highest output under lowest 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 WorkingLoadLimit 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' high-resolution 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: "with LR18B we are continuing our philosophy of bringing advanced transducer technology in our designs. The 18" is a new-generation transducer, fitted with a large, dual- 4.5" 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."
