Alcons Audio Debuts BC332 Self-Powered High-Output Cardioid Subwoofer
+- Print Email Share RSS RSS

Alcons Audio has introduced the BC332, a self-contained, high-output cardioid subwoofer system for both permanent and portable ground-stacked applications.

Following 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 loudspeaker.

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

The front side includes one 18-inch long-excursion woofer with 4-inch voice coil with double-spider and demodulation ring frame. It is mounted in a front-loaded configuration with proprietary X-Venting, a newly designed reflex port that takes more than 20 percent of the baffle surface and is designed to maximize the system’s breathing capacity, substantially increasing overall output while minimizing port-compression.

The rear side offers a single 15-inch long-excursion woofer with 4-inch voice-coil with double-spider and demodulation ring frame. It is also mounted in a front-loaded configuration, with proprietary Flank-Venting, a folded port design that enables optimal reflex-breathing, under minimal baffle dimensions, reducing destructive interference between speaker and reflex-vent.

The 2x 4 ohms 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 35 Hz (-3 dB).

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 optimization, protection and hybrid filtering processing. The ALC preset library contains cardioid settings for maximum rear- and side-ward attenuation.

As with 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 six-year limited warranty.
