Alcons Audio Launches QB242 Arrayable Subwoofer




The QB242 is a modular bass element to be used in both permanent and (limited) portable applications. It is designed as a fully-scalable low-frequency extension (LFE) system to the QR24 line-source column system, or as arrayable LFE system with any Alcons pro-ribbon system.

The QB242 can be stacked or flown in multiples, making it an ideal 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 thus be extended down to the lower frequencies by enlarging the LFE array length through adding extra QB242 modules. The lowest usable frequency of one single element is 35Hz.

The Q-systems are the perfect tool in applications where a high directivity and/or a very long throw is required, combined with HiFi output and concert SPL’s, like theatres, churches, Houses of Worship, mobile outdoor sound system and “acoustically challenging rooms.”

The two direct-radiating 12” Neodymium woofers are mounted in a vented chamber, with large bass reflex ports for excellent breathing capacity, increasing overall output while minimizing port-compression. The tight driver arrangement caters for optimal array coupling.

The integrated mounting hardware facilitates quick and easy coupling with other QB242 modules. The QB242 is powered and controlled by the ALC amplified loudspeaker controller.

Philip de Haan, head of Alcons Audio R&D said, “Our Q-series is the purest form of a line-source array, where we are able to acoustically obtain a pure, virtually side-lobe-free cylindrical projection, without the need for DSP-based beamforming. The Q-series is probably our most underestimated system, as listeners are always surprised by the phenomenal throw and razor sharp vertical directivity control of even a single QR element; and to experience a coherent QB array of 12m/39-ft tall in one of our reference projects is quite impressive!”
