The Alcons Audio BC332 is a self-contained cardioid subwoofer system for permanent and portable ground-stacked applications. Following the larger BC543 model, the BC332 offers directivity control, high output, accurate sub-bass response, for low-frequency extension of any Alcons pro-ribbon system.
A front-and-rear woofer configuration in combination with dedicated processing enables selectable cardioid low-frequency pattern control and high rear rejection (up to 18dB), without the need for additional cabinets.
A 18-inch long-excursion woofer with 4-inch 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 per cent of the baffle surface and is designed to maximise the system’s breathing capacity, substantially increasing overall output while minimising port-compression. On the cabinet rear, a single 15-inch long-excursion woofer with 4-inch voice-coil with double-spider and demodulation ring frame is mounted in a front-loaded configuration with Flank-Venting port; This folded port design enables optimal reflex-breathing, under minimal baffle dimensions, reducing destructive interference between speaker and reflex vent.
The 2x 4Ω system impedance provides optimal amplifier loading, reducing the required amplifier power and specification for full system response and maximum output. The frequency response starts at 35Hz (-3dB) and offers a ‘colourless’ low-frequency enhancement of any Alcons pro-ribbon sound system.
The BC332 is powered and controlled by the ALC amplified loudspeaker controller; Through the integrated processor, the ALC optimally drives the BC332 with specific response optimisation, protection and hybrid filtering processing. The ALC preset library contains cardioid settings for maximum rear-/side attenuation.
As all Alcons loudspeaker systems, the BC332 is SIS pre-wired for a very high damping factor (>10.000 under all loads/conditions); Through the SIS (Signal Integrity Sensing) circuit, the cable-length and connector resistance between the BC332 and ALC is dynamically compensated for.
The combination of complex internal panel lay-out and extensive bracing brings a rigid structure with a high enclosure stiffness from a relatively low-weight package. It is finished in Durotect scratch-resistant coating and comes with a six-year limited warranty.
