Alcons Audio has launched the BC543, a high-output cardioid subwoofer.
The BC543 is designed to cater for both permanent and portable ground-stacked applications. It's front and rear located woofer configuration combines with Alcons Digital Drive Processor, offering selectable cardioid, low-frequency pattern control and up to 18dB of rear rejection, with no need for additional cabinets.
The front of the unit features two AW18.6NDC/8 18-inch, long excursion woofers, along with a 5.3 inch voice-coil with vented triple-frame, Neodymium motor structure, carbon fibre cone and dust cap.
It's rear features a single AW18.6NDC/8 driver of the same configuration, with the unit's output being extended by 3.5dB in comparison to traditional 18" woofer designs, due to the extreme excursion capabilities of the design.
