• Alcons Audio introduces QB363 mkII bass system

    The QB363 mkII from Alcons Audio is a modular column bass system, designed as a low-frequency extension (LFE) system to the Q-series line-source column systems; However, it can be used as arrayable LFE system with any Alcons system.

    The QB363 mkII can be stacked or flown in multiples, as a building block to form bass arrays, for obtaining low frequency projection and throw control in acoustically challenging spaces or in long-throw applications. The QB363 mkII is also a convenient base for a slim profile stack system with the QRP40 point-source column.

    The three 12” transducers feature a dual-3.5” voice-coil Neodymium motor, said to enable a significantly-extended excursion, while maintaining a high sensitivity.

    The tightly-spaced, direct-radiating drivers are complemente by large, symmetrically-positioned bass reflex vents, increasing overall output while reducing port-compression. The ports are part of the cabinet’s integral structure, for increased rigidity under a minimal system weight.

    The 5.3 ohms system impedance makes it posible to drive an array of six 12” from one Alcons Sentinel channel.

    The QB363 is powered and controlled by the ALC amplified loudspeaker controller; Through the integrated processing and feedback, the ALC offers QB363-specific drive processing with optimal response and long-term reliability. The integrated factory presets in the ALC drive processor offer gain, phase, array-length and filtering matching with all Alcons pro-ribbon sound systems.

    Philip “Dr. Phil” de Haan, head of Alcons Audio R&D: “After the recent introduction of our QRP40 larger-format point-source column, we received many requests for a matching subwoofer to expand the QRP40 into a full-range stack system; At the same time, we also wanted a more economical solution for taller bass arrays, as the QB242’s bigger brother. Combining both demands lead to the QB363 mkII., plus the fact that the first edition of the QB363 already dates back to 2007. The Alcons Q-series is a family of real problem-solving solutions, that never fail to deliver in even the most challenging applications. The razor-sharp directivity of the point-source or modular line-source solutions enables a virtually side-lobe-free cylindrical projection, without the need for DSP-based beamforming.”

    Philip continues: “With the QB363, we extended the problem-solving power of the Q-series even further. By means of the simple PINM10 accessory, our QRP40 point-source column forms a very high-output sleek-design system with the QB363, providing a correct listening height, while maintaining full horizontal panning capabilities of the QRP40; This toe-in ability is a nice feature to obtain the perfect hearing experience; Our continuous driving force!”.
