Celestion has announcied that the CF0820BMB and CF0820M, two of its 8-inch (200 mm) diameter ferrite magnet, cast-aluminum-chassis cone loudspeaker drivers, are now available packaged individually for dealers and distributors to sell to retail.
The CF0820BMB is purpose-built for bass and mid-bass applications that’s well suited to two-way systems. It has a 2-inch (50 mm) multi-layer voice coil stated to provide 250 watts rms (AES standard) power handling and 93 dB sensitivity with an output frequency range of 50 Hz to 6 kHz. The half roll elastomer surround is designed to enable greater stability at extremes of excursion, along with improving modal distribution for reduced distortion. Balanced Airflow Venting (BAV) increases airflow around the coil and inner magnet assembly to provide enhanced cooling, preventing sensitivity loss through thermal compression.
The CF0820M is a dedicated midrange driver is designed for straightforward three-way systems, horn-loaded or line array applications. It is stated to deliver 250 watts rms (AES standard) power handling and 98 dB sensitivity, with an output frequency range of 150 Hz to 6 kHz. A copper sleeved pole is designed to reduce inductive rise for improved high-frequency performance. The low-profile aluminum chassis enables close packing in applications where multiple drivers are required, while an inverted dust cap helps with the close positioning of a phase plug where horn-loading is required.
Developed at Celestion’s headquarters in Ipswich, England, these loudspeakers are designed using specialist FEA (Finite Element Analysis) modelling techniques, enabling the Cthe engineering team rapidly to achieve increases in performance that include greater efficiency and lower distortion.
