Over a decade ago, Radian Audio Engineering
went into business with a commitment to manufacture loudspeaker components that
accurately reproduce the full frequency range of the audio spectrum. They began
by building coaxial loudspeakers and compression drivers. The Radian 951 PB,
with a 4.” diaphragm, represents the refinement of their design efforts in 1.44”
exit-format compression driver technology. All Radian compression drivers
feature heat-treated structural alloy aluminum diaphragm domes which form an
optimum balance of strength and low weight. This is a key factor in extending
high frequency response.
Radian diaphragms utilize a Mylar® surround, which not only enhances the
diaphragm’s reliability, but eliminates fatigue which destroys other
compression driver diaphragms. In addition to being virtually indestructible,
Mylar® surrounds provide excellent dampening characteristics which translate
into smooth, low-distortion, linear output devoid of the resonant peaks
typically present in diaphragms made with metal surrounds. Beyond the obvious
advantages of our Mylar®-aluminum composite construction, Radian diaphragms
utilize high temperature voice coil formers and advanced adhesives which allow
Radian compression drivers to sustain high RMS and peak power levels over
extended periods of time.
Radian diaphragm assemblies are self-aligning and may be rapidly serviced in
the field by simply removing the three screws on the driver’s backcap and carefully
replacing the old unit with the new one.
Superior sound quality, unparalleled power handling, extended high frequency
response, and high reliability make Radian compression drivers the preferred
choice of loudspeaker systems manufacturers, consultants, contractors,
designers, and engineers around the world. They are ideal for use in high
output, high power touring sound systems and stage monitors, while their low
distortion, high fidelity, and linear response deliver clear, crisp music and
speech for theatrical, auditorium, stadium, convention and church installations.
