New York, NY (December 24, 2012)—Alcons Audio has introduced the QR24 line-source array column, a modular, 2-way column loudspeaker to be used as a vertical array system, for both permanent and limited portable applications.

The QR24 measures 26” tall and is fitted with 4x 6.5” woofers and two purpose-built 12” pro-ribbon drivers. Specifically for this system, the RBN03 pro-ribbon platform was developed in an effort to provide non-compressed HiFi sound quality, low distortion possible and less mounting depth. This accommodates a co-axial driver arrangement with the LMF transducers, which are, at the same time, actively cooling the RBN drivers for further power compression reduction.

By using only two 12” RBN drivers, the system’s active frontal radiation is reportedly close to 90%; The resulting vertical dispersion is said to offer SPL-independent, intelligibility over distance without the necessity of DSP-based beam-shaping.

The projection pattern in the horizontal / non-coupling plane is 80-degrees (-6dB) and in the vertical / coupling plane, it is 6-degrees (single column). Each purpose-designed 12” RBN driver has a peak power handling of 2.000W (200 msec), creating a e system headroom of 4.000W from 1kHz up. The frequency response is -3dB flat between 74Hz. to 20.000Hz, to match an accompanying subwoofer system. The passive filtering allows up to 3 QR24 modules to be combined on one amplifier channel, with an array length of 2meter/7ft.

The QR24 is powered and controlled by the Sentinel amplified loudspeaker controller; Through the integrated processing and feedback, the Sentinel offers QR24-specific drive processing.
