 Celestion has added two new additions to its CF range of cast-aluminium, ferrite-magnet drivers for  tour sound and fixed install applications. 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 applications in two and three–way systems.

The 1200Wrms, CF1540HD has a 97dB sensitivity (1W, 1m), and a four-inch inside/outside voice coil, wound on both sides of the former for better heat dissipation preventing sensitivity loss through thermal compression. Purpose-built for subwoofer applications, the CF1540HD features a phase-matched double suspension system for a more balanced and symmetrical performance throughout the entire excursion of the cone for significant distortion reduction. Both drivers incorporate twin demodulation rings, employed to reduce harmonic and intermodulation distortion. Additionally, each one 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.The CF drivers are also built with weather-resistant cones, enabling them 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.  "The arrival of the CF1230F and the CF1540HD makes the CF range very comprehensive; with 6, 8, 10, 12, 15 and 18-inch drivers now available," saidd Nigel Wood, Celestion managing director. "Whether you're looking for high-quality midrange drivers for a line array installation, a powerful bass reflex subwoofer, or all points in between, there's a CF driver to suit your application requirements."
