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 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 "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.
