Haut-parleur 18" woofer Radian 2218
[2218-8] Avis/Critiques The Radian 2216 15” 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 124 dB.
