Alcons Audio Introduces QRP20 Pro-Ribbon Point Source Column

Designed for applications where high-fidelity response needs to be projected with wide horizontal and narrow vertical coverage, such as in acoustically challenging environments.

Alcons Audio has announced the introduction of the QRP20, a new two-way column array designed to provide high-Q directivity for increased projection control that can be used as a vertical system in both permanent and portable applications.

With a slim profile that measures 5.9 inches wide and deep, it is specifically designed for applications where high-fidelity response needs to be projected with wide horizontal and narrow vertical coverage, such as in acoustically challenging environments and applications where intelligibility-over-distance is required.

It’s loaded with an RBN401 4-inch pro-ribbon driver, offering a natural cylindrical wavefront, that’s mounted on a “Morpher” lens. The QRP 20 is stated to offer peak power handling of 800 watts (at 200 ms) with a 1:15 RMS-to-peak dynamic range, while also stated as providing maximum gain before feedback. Due to the “compression-less” principle of the pro-ribbon transducer, the system is specified to have a fully linear response at any SPL.

The RBN401 is mounted in a D’Appolito loudspeaker configuration with four custom-designed 5-inch woofers in a sealed cabinet. The woofers incorporate proprietary Active Coil technology designed to foster very low-distortion low-frequency reproduction.

The QRP20 is powered and controlled by the ALC amplified loudspeaker controller. Through the integrated VHIR processing, amplifier stages and Signal Integrity Sensing feedback circuit, the ALC offers QRP20-specific drive processing to deliver maximum sound quality with increased headroom.

Philip “Dr. Phil” de Haan, head of Alcons Audio R&D, states, “The essence of the Q-series is the isophasic wavefront of our pro-ribbon mid/high frequency transducer technology, delivering the razor-sharp, side-lobe free projection control in the vertical plane and throw, the Q-series is known for.

“Following the success of our larger QR24 system, that utilizes this line-source wavefront coupling ability in a modular configuration, we received many requests for a smaller, non-modular single cabinet system, while maintaining the controlled projection characteristics. The result is the QRP20 point-source column.”

The QRP20 is available with 90-degree (QRP20/90) and 120-degree (QRP20/120) horizontal dispersion and comes with Alcons Audio’s six-year “no hassle” warranty.

de Haan concludes, “We’ve seen in many, typically acoustically challenging applications, that the necessity for controlling the sound projection in order to get a satisfactory intelligibility lead to severe sacrifices on sound quality and dynamic output with existing solutions, either passive or steered. The QRP20 is proof that an exceptional, SPL independent intelligibility and throw is possible without any sacrifice on sound quality and performance, regardless of system size.”
