The latest Alcons Audio LR24/120 mid-size line speaker array is aimed at medium to larger live applications. The LR28 larger format line array module, designed for arenas, stadiums and major outdoor events is based around the company’s pro-ribbon transducer technology.
The three-way, bi-amped LR24/120 features the bespoke RBN1202rs 12-inch pro-ribbon transducer with acoustically and electronically symmetrical component configuration, delivering a natural cylindrical wavefront with unique pattern control in both the vertical and horizontal plane. Without any distortion-inducing horn construction, the transducer produces pure sound up to the highest frequencies, the coherence of the vertical dispersion delivering perfect inter-cabinet coupling for ultimate HF throw and wind stability. Thanks to the RBN1202’s power handling of 2500W, enabled by its 12” voice-coil, and an RMS-to-peak ratio of 1:15 from 1 kHz to 20 kHz, remarkable intelligibility is complemented by maximum dynamic headroom reserve.
The pro-ribbon driver is complemented by a mid-frequency section comprising two 6.5-inch midrange transducers with a neodymium motor structure; The low-frequency section features a new generation of 12-inch transducers, fitted with a dual 3.5-inch voice coil neodymium motor. This enables a significantly extended excursion with high sensitivity for very accurate, high output bass, with low distortion.
With a benchmark-setting fast impulse response and low distortion, the LR24/120 claims to deliver perfect intelligibility and non-compressed, identical tonal balance at any SPL. As with all Alcons L-series systems, this is assisted by Signal Integrity Sensing (SIS) pre-wiring. This circuit ensures dynamic cable/connector compensation between the LR24/120 and the Sentinel amplified loudspeaker controller which powers it, providing undistorted, natural sound reproduction regardless of cable length and amplifier impedance load. Dedicated system configuration presets feature the VHIR flat-phase processing.
The patented flying system facilitates both compressed and non-compressed suspension, while enabling angle-setting on the cabinets without lifting the array. It has a WLL of 24 cabinets under 10:1 safety.
