Alcons Audio has announced the introduction of the new QRP40/90, a two-way point-source column loudspeaker with high-Q directivity designed to provide increased projection control, at the upcoming ISE 2023 show in Barcelona (stand 7K600).
It’s intended to be deployed vertically in both permanent and portable applications, particularly acoustically challenging environments and situations where musicality and intelligibility-over-distance is required.
Loaded with a RBN1203 12-inch pro-ribbon driver — one of the two from its modular sibling QR24 — on a “Morpher” lens, the loudspeaker is designed to provide high SPL-independent throw-efficiency and projection control due to the pro-ribbon’s all-natural cylindrical wavefront. The 90-degree horizontal dispersion is designed to provide consistent audience coverage, while the 20-degrees isophasic directivity caters for the side-lobe-free projection up to the highest frequencies.
The RBN1203 driver is mounted in a coaxial configuration with an array of eight (8) woofers in a sealed cabinet. The custom-design 5-inch woofers utilize proprietary Active Coil technology for low-distortion LF reproduction. The acoustical LF array length assists the QRP40 in an extended vertical projection control and increased output in the low-mid frequency range.
Philip “Dr. Phil” de Haan of Alcons says, “The introduction of the QRP40 follows on the heels of that 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.
“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.”
Mounting options include wall-, truss-, stand- and sub-stack mount. The optional ACO color scheme provides for an inconspicuous, low-profile presence.
de Haan: “Combining our multiple-patented horizontal and vertical dispersion control to beyond 20 kHz, 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 recognising the Q-series as a unique tool in their toolbox.”
