Experience True High-Resolution Sound on the Road
Car audiophiles craving a true audiophile-grade listening experience now have something extraordinary to get excited about. Introducing CDT Audio’s NEW High-Resolution Audio coaxial component systems, engineered to extend frequency response to an astonishing 50,000 Hz - well beyond conventional designs.
At the heart of this breakthrough is the ES-1200iS, the high-energy, ultra-wide-range tweeter serious listeners have been waiting for. While some may call a 50 kHz extension excessive, CDT Audio engineers know better: these ultra-high frequencies preserve the ambient details that bring music to life, adding realism, nuance, and character you can actually hear.
The ES-1200iS delivers higher efficiency and an exceptionally flat on- and off-axis response, ensuring consistent sound throughout the cabin. Just look at the on/off-axis curves below—especially the 45-degree response, where the ES-1200iS remains remarkably flat all the way to 15 kHz. This level of performance translates directly into audible benefits: enhanced openness, greater clarity, and a more natural soundstage thanks to superior power response compared to conventional tweeters.
Choose a High-Resolution Audio (HRA) Coaxial System with the woofer size that perfectly fits your vehicle—and rediscover your music with the detail, air, and precision it deserves.
