Alcons Audio is now presenting its new BQ211 subwoofer, which extends the low frequency response of the company’s pro-ribbon systems for both permanent and portable applications.

It is the first introduction of the upcoming LR24 mid-sized pro-ribbon line-array touring system.

 

The BQ211 is a double-tuned, quarter-wave loaded subwoofer system which is designed to offer maximum, prolonged high impact SPL performance from a comparatively small footprint, the company says.

 

It contains a large displacement 21” Neodymium transducer with an all-carbon fibre cone, for high pressure loading, plus a force-ventilated 5.3" voice-coil. The latter is mounted in a vented triple-spider frame and features optimised low resistance impedance and a port-vented magnet structure, to reduce power compression and prolong performance.

 

The internally-braced 15mm birch cabinet features double-tuned, high-pressure loading, through a rounded 236mm/9.3-in diameter low-tuned bass-reflex vent and wide, high-tuned quarter wave tunnel.

 

Finished with Alcons Durotect flexible and scratch-resistant coating, 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, enabling controlled directional LF dispersion.

 

It is powered and controlled by Alcons ALC series amplified loudspeaker controllers, whose SDP (Speaker Drive Processor) circuits offer BQ211-specific drive processing with response optimisation, dedicated power and excursion protection, hybrid filtering and cardioid processing. Additionally, through the SIS (Signal Integrity Sensing) circuit, the cable-length and connector resistance between the BQ211 and ALC is said to be completely compensated for, with a damping factor of 10.000, designed to further increase response accuracy.

 

With a frequency response of 33Hz - 150Hz (+/- 3dB) and an SPL that needs to be felt instead of read, the BQ211 is a wideband subwoofer with high SPL performance down to the lowest frequencies, according to Alcons. Yet, measuring 590 x 746 x 986mm (23.2 x 29.4 x 38.8-in.) and weighing 72kg/159lb, it is a described as a portable unit with a small footprint.

 

Part of The Ribbon Network inventory - Alcons’ global dry-hire network - the BQ211 has a wide variety of uses and comes with a 6 year limited warranty.
