4” VOICE COIL 600 WATTS RMS
2216
15” EXTENDED LOW FREQUENCY LOUDSPEAKER
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.
