The QB242 can be stacked or flown in multiples

Alcons Audio has released a modular bass element serving as either a fully scalable low-frequency extension system for the QR24 line source column system or as an arrayable LFE system with any of the manufacturer’s pro-ribbon systems. The QB242 can be stacked or flown in multiples, serving as a building block to form bass arrays for obtaining low-frequency projection and throw control in acoustically challenging spaces or over longer distances.

The controlled (cylindrical) projection of the QR24 can be extended down to the lower frequencies by enlarging the LFE array length and adding extra QB242 modules. According to Alcons, the lowest usable frequency of one single element is 35Hz.

The subwoofer’s two direct-radiating 12-inch neodymium woofers are mounted in a vented chamber, with large bass-reflex ports that increase overall output while minimising port compression. The tight driver arrangement caters for optimal array coupling, while the 8Ω system impedance makes for an efficient amplifier channel loading when assembling arrays of multiple units.

The QB242 is powered and controlled by the ALC amplified loudspeaker controller, which offers QB242-specific drive processing. Factory presets integrated in the ALC drive processor offer the latest VHIR processing, with gain, phase and filtering matching with all Alcons top systems. The integrated mounting hardware also facilitates coupling with other QB242 modules. The QB242 is finished in Durotect coating and comes with a six-year warranty.
