Alcons unveils column loudspeaker for vertical arrays

Alcons Audio has released the QR24/110, a modular two-way column loudspeaker that can be used as scalable vertical array system, for permanent and some portable applications.

It offers 1:1 linear sound reproduction and combines a symmetrical acoustic design with the patented 110-degree horizontal dispersion of the RBN High Frequency drivers (up to 20 kHz). The loudspeaker uses two 12-in RBN pro-ribbon transducers for mid-high frequencies.

Each RBN1203 12-in pro-ribbon driver has a peak power handling of 2.000W (200 msec), creating a system MHF headroom of 4.000W from 1kHz up.

The low-mids are handled by four high-excursion, vented 6.5-in transducers, which are co-axially mounted behind the pro-ribbon drivers, delivering a frequency response of 74 Hz – 20.000 Hz (-3dB).

Projection can be extended down to the lower frequencies by enlarging the array length through adding extra QR/QM modules (extending the “near field”). Up to two QR24 units can be combined on one tripod stand, forming a 1.32m tall array. In flown configuration, up to 11 cabinets of QR24 can be connected, with the integrated flying hardware under a safety-rating of 10:1, forming arrays more than 7metres tall. Passive filtering allows up to three modules to be combined on one amplifier channel.

The QR24/110 is powered and controlled by the ALC amplified loudspeaker controller that has integrated processing and feedback.

Trade marked Signal Integrity Sensing pre-wiring is designed to compensate for speaker cable/connector influences between the QR24 and ALC.

The QR24 is also available as QR24/80, with 80-degree horizontal dispersion and can be combined with the QR24/110 in the same array.

Certified EASE data for the QR24’s with a 1-degree resolution accuracy is available on the Alcons website.
