Alcons introduces carbon-coned subwoofer
Published: PRODUCTS
Alcons Audio is now shipping its new BQ211 subwoofer, which extends the low frequency response of the company’s pro-ribbon systems for both permanent and portable applications.
The BQ211 is a double-tuned, quarter-wave loaded subwoofer system which the manufacturer designed to offer high impact SPL performance from a comparatively small footprint. It contains a 21-inch Neodymium transducer with an all-carbon fibre cone plus a force-ventilated 5.3-inch voice-coil. The latter is mounted in a vented triple-spider frame and features low resistance impedance and a port-vented magnet structure.
The internally-braced 15mm birch cabinet features double-tuned, high-pressure loading, through a rounded 236mm/9.3-inch diameter low-tuned bass-reflex vent and wide, high-tuned quarter wave tunnel. It has slider feet on the bottom and sides, enabling the stacking of multiple BQ211’s into vertical low frequency arrays. The additional front-positioned NL4 connector caters for reverse connection in cardioid arrays.
It is powered and controlled by Alcons ALC series amplified loudspeaker controllers, which offer BQ211-specific drive processing with response optimisation, dedicated power and excursion protection, hybrid filtering and cardioid processing. Additionally, the cable-length and connector resistance between the BQ211 and ALC can be compensated for.
It is the first introduction of the upcoming LR24 mid-sized pro-ribbon line-array touring system, and has a frequency response of 33Hz - 150Hz (+/- 3dB) and measures 590 x 746 x 986mm with a weight of 72kg.
