- High-performance line-array LFE system for medium to larger applications
- Stackable and flyable with LR18 line-array or in separate curved arrays
- Maximum deployment flexibility also in cardioid - and end-fire arrays
- Neodymium dual-coil 18” driver with lowest possible distortion
- SIS™ pre-wired for very high system damping and further reduced distortion
- Front-positioned NL4 connector for easy cardioid connection
The LR18B is the dedicated low-frequency extension to the LR18 pro-ribbon line-array. It can also be combined with any other Alcons pro-ribbon system, in both permanent and portable applications.
The front-loaded system delivers a super accurate bass and sub response with highest output under lowest distortion, due to the super long-stroke 18” woofer. This new-generation transducer is fitted with a large, dual- 4.5” voice-coil Neodymium motor, enabling a significantly-extended excursion*, while maintaining a high sensitivity. Specific attention in this design has been paid to obtain lowest possible distortion. The Max-Vent™ port design combines further increased output with low power compression. *(not included in SPLpeak spec).
Optimal deployment flexibility is guaranteed: The LR18B 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.
Rated for a high WorkingLoadLimit with 10:1 safety ratio, the versatile rigging system, with front and rear splaying possibility, enables 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.
Mobile (cardioid) stacks of up to 3 units can be transported through the PRRGLR18B pre-rig, including stack-specific softcover.
For full system performance, the LR18B is to be driven and controlled by the ALC 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.
