Product description
Preliminary information
The GR20 is a 2-way loudspeaker designed as high performance point-source sound system, for both portable as well as permanent applications.
The system brings the unsurpassed natural, dynamic and ultra-low distortion Alcons signature sound in a compact, yet very powerful package with a relative small footprint.
The system features the Alcons-proprietary RBN602rs 6” pro-ribbon driver technology, offering a non-compressed, fully linear sound reproduction at any SPL, with up-to-90% less distortion.
Its fast impulse response, “compression-less” principle and flat frequency response enable a 3 to 6dB better gain-before-feedback than traditional systems, resulting in a perfect intelligibility in even acoustically challenging applications.
The pro-ribbon’s extreme peak power handling of 1.250W (for 200 ms, which is 10x the industry standard) results in a 1:15 RMS-to-peak dynamic range, which means in practice a virtually unlimited headroom.
The patented (80 x 50-degrees) directivity offers a very controlled and consistent projection up to the highest frequencies for a wide stereo sweet-spot and excellent coverage in even elevated listening areas. The revolvable waveguide provides this projection accuracy also with a horizontally positioned GR20.
The RBN602 driver is mounted in a tight-packed, vertically symmetrical configuration with two mid-bass woofers for optimal acoustical coupling and perfect projection coherency.
The custom-designed 10” Neodymium woofers feature Active Coil™ technology for extremely low-distortion LF reproduction, a perfect match with the MHF pro-ribbon technology.
Their two 3-in. voice-coils in passive-filtered tandem with the pro-ribbon’s 6-in. voice coil deliver a very dynamic, high output performance from one single amp channel.
As integral part of the Alcons eco system, the GR20 is to be driven by an ALC amplified loudspeaker controller; Through the factory presets with integrated VHIR™ processing, 192kHz AES3 digital inputs and audiophile amplifier stages, the ALC enables the GR20 to deliver a natural 1:1 sound quality with maximum output efficiency and utmost operation reliability.
The Signal Integrity Sensing™ pre-wiring ensures complete cable/connector compensation between the GR20 and SIS™ featured ALC; The resulting system damping factor of 10.000 offers a further reduced distortion, regardless of cable length and amplifier impedance load.
