PRODUCT INFO The Radian 2218 18" low frequency transducer produces extremely high levels of bass energy. This woofer is designed as an extended low frequency device, used as a subwoofer or general purpose LF transducer. Notably this transducer will perform very well in a 4.5 cubic foot enclosure. Integral to this design is a composite ribbed cone, reinforced with Kevlar . The voice coil is edge wound aluminum for better transient response, however our advanced adhesives give it the power handling capacity of more conventional copper voice coils. With 750 watts AES power handling and a high-energy magnetic structure with a venturi cross section to increase ventilation efficiency, the output sensitivity is 96 dB (one watt, one meter) with a continuous sound pressure level of 123 dB.
