Alcons Audio is now shipping the LR18B line-array bass following its debut at this year’s Prolight + Sound in Frankfurt and InfoComm in the USA.

The LR18B is the 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 is said to deliver an 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 allows for top/sub combinations with any Alcons pro-ribbon system.

The rigging system 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), the company’s high-resolution 3D simulation program. For full system performance, it is recommended that the LR18B is driven and controlled by the ALC Sentinel amplified loudspeaker controller.

The Signal Integrity Sensing pre-wiring ensures cable/connector compensation between the LR18B and ALC in order to increase response accuracy and reduce both linear and non-linear distortion.

Philip “Dr. Phil” de Haan, head of Alcons R&D, said: “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.”
