  • Radian Audio's model 2218, 18" extended low frequency loudspeaker produces impressive amounts of deep, clean bass energy.

    It is most often utilized in dedicated sub-woofer systems in live sound and nightclub applications. The Radian 2218 has a 4" edgewound voice coil for superior power handling capability and performs very well in enclosures as small as five and one half cubic feet.

    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 600 watts RMS 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.
