- Double-tuned, bass-reflex loaded cardioid-control subwoofer system
- Single 18” woofer with 15” woofer in cardioid arrangement
- Large vents for improved breathing and low port compression
- Selectable cardioid patterns with up to 42dB rearward rejection
- SIS pre-wired for very high damping and further reduced distortion (with ALC)
- Low impedance for efficient amplifier loading
Product description
The BC332 is a self-contained, high-output cardioid subwoofer system for both permanent and portable ground-stacked applications. It is designed to offer a 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 system offers selectable cardioid low-frequency pattern control and excellent rear rejection (up to 42dB), 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 port takes more than 20% of the baffle surface and is designed to maximize the system’s breathing capacity, increasing overall output while minimizing 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.
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 is fitted with 6 handles for easy logistics + stand mount adapter (road-version).
The BC332 is powered and controlled by the ALC amplified loudspeaker controller; Through the integrated processor, the ALC offers BC332-specific drive processing with response optimisation, dedicated power and excursion protection, and hybrid filtering.
The preset library contains cardioid settings for maximum rear-/side-ward attenuation. The 4 ohms impedance offers efficient amplifier loading.
Through the SIS™ (Signal Integrity Sensing) circuit, the cable-length and connector resistance between the BC332 and ALC is completely compensated (system damping factor >10.000), for further increased accuracy and controlled cone-travel, resulting in a tighter sub and bass response.
