Product description
The LR15/90 is a 2-way, “ultra-compact” format line-source sound system, combining the highest sound quality possible with high SPL capabilities and throw in a very compact form factor.
By implementing Alcons’ pro-ribbon technology for mid and high frequencies, a super-fast impulse response with up-to-90% less distortion is achieved. This enables the LR15 to offer a fully intuitive linear response, with perfect intelligibility and non-compressed identical tonal balance at any SPL.
The all-natural cylindrical wavefront of the multiple-patented RBN502rs 5” pro-ribbon transducer with 5” voice-coil and the symmetrical component configuration bring a natural, unique pattern control in both the vertical as well as the horizontal plane up to the highest frequencies.
The pro-ribbon’s power handling of 1100W and RMS-to-peak ratio of 1:15, caters for a superb intelligibility and throw with a dynamic headroom reserve, even under the highest outputs.
The LF-section consists of two next-gen 6.5” transducers; a perfect hybrid of a woofer and mid-bass driver featuring a 2-in. dual-coil motor structure with significantly-extended excursion. The woofers are loaded by FlowVent™ ports, providing optimised flow with minimal port compression while extending the usable LF response down to 53Hz.
The resulting super accurate low-mid and bass response with class-leading output under lowest distortion possible, is a perfect match with the pro-ribbon MHF.
The LR15 is driven by the Sentinel amplified loudspeaker controller, optimising the system’s response by specific VHIR™ drive processing and feedback for each array configuration, including presets for phase-matched low-frequency extensions.
The Signal Integrity Sensing™ pre-wiring ensures dynamic cable/connector compensation between the LR15 and ALC; This offers a 1:1, undistorted natural sound reproduction, regardless of cable length and amplifier impedance load (system damping factor 10.000).
The 3-point rigging and transport system enables angle-setting on the cabinets without lifting the array, resulting in safer and faster set-up with minimal handling and a WLL of 18 cabinets under 10:1 safety. The LR15 is available with a 90° (LR15/90) or 120° (LR15/120) horizontal dispersion.
