Alconsintroduces the QR24 line-source array column, a modular 2-way column loudspeaker.

It can be used as vertical array system, for both permanent and (limited) portable applications.

 

Due to its modularity, throw and low-frequency directivity (“near field”) can be increased by extending the array length; Multiple individual mid-high frequency lobes can be made, by using the QM low-mid fill columns.

 

The QR24 measures 66cm / 26” tall in length, and is fitted with 4x 6.5” woofers and two purpose-built 12” pro-ribbon drivers; The “RBN03” pro-ribbon platform was developed. This is designed to accommodate 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.

 

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 virtually infinite system headroom of 4.000W from 1kHz up, according to Alcons.

 

The frequency response is -3dB flat between 74Hz. to 20.000Hz, to match a accompanying subwoofer system, catering for a bi-amped, three-way 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.

 

The Signal Integrity Sensing pre-wiring is designed to ensure cable/connector compensation between the QR24 and ALC; This offers a 1:1, undistorted natural sound reproduction, regardless of cable length and amplifier impedance load (system damping factor >10.000 down to 2 ohms).
