Dutch manufacturer Alcons Audio will be presenting the BC332, the most compact cardioid subwoofer in its range. The BC332 is a self-contained, high-output cardioid subwoofer system for both permanent and portable ground-stacked applications. Following in the footsteps of its bigger brother, the BC543, the BC332 is designed to offer a directivity-controlled, high-output, tight and accurate sub-bass response, for low-frequency extension of any Alcons pro-ribbon system. By means of a front and rear located woofer configuration, in combination with dedicated processing, the BC332 enables selectable cardioid low-frequency pattern control and up to 18dB rear rejection without the need for additional cabinets. On the front side, one 18in long-excursion woofer with a 4in voice-coil with double-spider and demodulation ring frame is mounted in a front-loaded configuration, with X-Venting. This newly-designed reflex port takes more than 20% of the baffle surface and is designed to maximise the system’s breathing capacity, increasing overall output while minimising port-compression. On the rear side, also front-loaded, sits a single 15in long-excursion woofer with the same voice-coil and ring frame system, this time mounted with a Flank-Venting port. This folded port design enables optimal reflex-breathing, under minimal baffle dimensions, and reduces the destructive interference between the speaker and reflex-vent. The BC332 is powered and controlled by the Alcons ALC amplified loudspeaker controller, which drives the BC332 with specific response optimisation, protection and hybrid filtering processing.
The ALC preset library contains cardioid settings for maximum rear- and side-ward attenuation.
Like all Alcons loudspeaker systems, the BC332 is SIS (Signal Integrity Sensing) pre-wired, so through the SIS circuit, the cable length and connector resistance between the BC332 and ALC is dynamically compensated for. This, the manufacturer states, results in a very clean and tight sub and bass response. Stand: 6N134 www.alconsaudio.com
