When combined with the Control 40CS/T, the Control 42C offers an extremely natural sounding and powerful subwoofer-satellite system that is perfect for applications requiring wide bandwidth and superior sonic performance with minimal visual impact. For full-range wide-bandwidth performance, either 2 or 4 Control 42C mid-high speakers can be driven from the Control 40CS/T subwoofer (or from a Control 50S/T surface-mount or Control 60PS/T in-ceiling subwoofer). The crossover for this subwoofer-satellite system is included in the subwoofer, and the system can be driven either low-impedance or from a 70V/100V distributed speaker line.
