For over two decades Radian Audio has manufactured some of the world’s finest compression drivers. We now produce a wide variety of models and sizes for virtually any application or requirement. Radian Audio’s compression drivers sound better because of our amazing diaphragm design. Our compression driver diaphragms are made of proprietary annealed aluminum with Mylar TM surrounds and in numerous independent lab tests have less measurable distortion than the competition. The result? Less distortion, less listening fatigue and a better listening experience for all.
