1.4" exit compression driver. 3" coil, aluminum alloy dome with Mylar surround diaphragm. 111dB 1W/1M. 75 watts AES power handling. Driver includes two bolt circle patterns - a standard 4" and a second one of 3.5" shifted by 45º, for attachment to horns.
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. We began by building coaxial loudspeakers and compression drivers. The Radian 636PB, 745PB and the 835PB, with a 3.0" diaphragm, represent the refinement of our design efforts in 1.4" 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 replacing the old unit with the new one.
Superior sound quality, unparalleled power handling, extended high frequency response and high reliability make our 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 delivers clear, crisp music and speech for theatrical, auditorium, stadium, convention and church installations.
