The new Alcons QRP40 Pro-Ribbon Point-Source Column is specifically designed for applications where ultimate fidelity response needs to be projected with a very precise coverage, ideal in acoustically challenging environments, or applications where musicality and intelligibility-over-distance is required.
Loaded with a RBN1203 12" pro-ribbon driver, one of the two from its modular sibling QR24, on a "Morpher" lens, the system offers an exceptional, SPL-independent throw-efficiency and projection control, due to the pro-ribbon’s all-natural cylindrical wavefront. The patented 90-degrees horizontal dispersion offers a consistent audience coverage, significantly extending the "sweet-spot", while the 20-degrees isophasic directivity caters for the side-lobe-free projection up to the highest frequencies.
Its fast impulse response, "compression-less" principle and unusual high peak power handling (2.000W @ 200ms) enable a perfect intelligibility and intuitive linear response from the lowest to the highest SPL with a 1:15 dynamic range, while offering a maximum “gain-before-feedback” up to directly in front of / under the system.
The RBN1203 driver is mounted in a co-axial speaker configuration with an array of eight (8) woofers in a sealed cabinet. The custom-design 5" woofers feature Active Coil technology for extremely low-distortion LF reproduction, a perfect match with the MHF pro-ribbon technology. The acoustical LF array length assists the QRP40 in an extended vertical projection control and increased output in the low-mid frequency range, at the same time enabling a smooth but powerful roll-off to additional subwoofers.
"The introduction of the QRP40 follows on the heels of the QRP20 point-source column. Although it may look like "just" a larger version of the QRP20 on the outside, we took a different path in this development," shares Philip "Dr. Phil" de Haan, co-founder, senior R&D engineer, initiator of multiple patents, and father of the company's high-output pro-ribbon technology. "The initial plan of the QRP columns was to develop only the QRP20 and offer a low-mid frequency extension column, just as we have in the QR24 with the modular QM24. However, in the prototyping and simulation stages, we found that the directivity control of such a modular asymmetric approach was poor. So instead we decided to develop a dedicated, larger symmetrical system for more throw and SPL capability, with the excellent projection control characteristics the Q-series is known for."
The system brings the dynamic and ultra-low distortion Alcons signature sound in a very slim and unobtrusive package; The different mounting options for wall-, truss-, stand- and sub-stack mount, together with the optional ACO color scheme provides for an inconspicuous, low-profile presence in any application.
"Combining our multiple-patented horizontal and vertical dispersion control to beyond 20kHz, with the throw, gain-before-feedback and crystal clear ultra-low distortion signature sound of our pro-ribbon transducers, it’s easy to understand why sound designers around the globe are recognizing the Q-series as a unique tool in their toolbox," concludes Phil de Haan.
Alcons Audio will promote the latest range of Pro-Ribbon solutions for installation, live performance and cinema sound, including the famous Pro-Ribbon Immersive Experience at ISE 2023 (booth 7K600). The show will be also an opportunity to celebrate the company's 20th anniversary and the recent opening of Alcons newest facilities in The Netherlands, with a total of 4700m2 / 50,000sq. ft, offering ample expansion and increasing production, while bringing down lead times.
