475 - 1″ Exit Compression Driver

More than three decades 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 450 and 475, with 1.75” diaphragms, represent the refinement of our design efforts in 1” 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 typicall
