Alcons Audio has announced the introduction of the QB363 mkII, a new modular column bass system designed as a low-frequency extension (LFE) element for the company’s Q-series line-source column systems, and it can also be used as arrayable low-frequency component with any Alcons system. It will be highlighted at the upcoming InfoComm 2023 show in Orlando at the Orange County Convention Center.
The QB363 mkII can be stacked or flown in multiples in serving as the building block to form bass arrays for obtaining low-frequency projection and throw control in acoustically challenging spaces and/or long-throw applications. The controlled (cylindrical) projection of the Q-series can thus be extended down to the lower frequencies by enlarging the LFE array length through adding extra modules.
It can also act as the base for a slim profile stack system with the QRP40 point-source column for applications where high-quality performance with increased projection control needs to be combined with an unobtrusive design appearance.
The new-generation 12-inch transducers have dual-3.5-inch voice-coil neodymium motors that are designed to enable extended excursion while maintaining a high sensitivity. The tightly-spaced direct-radiating drivers work with large, symmetrically-positioned bass reflex vents to increase 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-ohm system impedance is intended to make for efficient amplifier channel loading when assembled in multiples. The QB363 mkII is powered and controlled by the ALC amplified loudspeaker controller offering QB363-specific drive processing with optimal response and long-term reliability. The integrated factory presets in the ALC drive processor supply 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, states, “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.
“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!”
