The 500Wrms, 12-inch CF1230F has a nominal sensitivity of 98dB (1W, 1m). With a three-inch, copper-clad aluminium voice coil. It is particularly suited to bass - midrange applications in two and three–way systems. CF1230F incorporates a demodulation ring, employed to reduce harmonic and intermodulation distortion. Additionally, it features Celestion’s Balanced Airflow Venting technology, rapidly taking heat away from the magnet assembly, cooling the motor system to counteract the effects of thermal compression more effectively.
This driver is also built with a weather-resistant cone, enabling it to be used in outdoor sound reinforcement systems. Additionally, the cone of the CF1230F incorporates a waterproof coating, so that this driver can be used in more challenging environments.
