Alcons BC332 Compact Subwoofer

Alcons BC332 Compact Subwoofer, front and back viewAlcons’ BC332 self-contained, high-output cardioid subwoofer system is designed for both permanent and portable ground-stacked applications. Like the bigger 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.

More details from Alcons Audio (www.alconsaudio.com):

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 rear rejection (up to 18dB), without the need for additional cabinets.

On the front side, one 18” long-excursion woofer with 4-in. 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, substantially increasing overall output while minimising port-compression.

On the rear side, a single 15” long-excursion woofer with 4-in. 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 4 ohms system impedance caters for optimal amplifier loading, reducing the required amplifier size and specification for full system response and maximum power output. The frequency response starts at 35Hz (-3dB) and offers a “colorless” 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-ward 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 controlled cone-travel results in a very clean and tight sub and bass response.

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 6 years limited warranty.
