Celestion will be unveiling new additions to its next-generation CF Series of high-end ferrite magnet drivers at the upcoming Winter NAMM show in Anaheim (booth 4676).

The new 18-inch, cast aluminum frame, ferrite magnet, low-frequency drivers are well-suited to use in high-end, professional sound reinforcement.

The CF1830E is designed to be a multi-purpose loudspeaker driver for reflex, scoop bass or horn-loaded subwoofers as well as a bass unit in a large multi-way system. The CF1830E hass a 3-inch/75mm multi-layer voice coil and delivers 700 watts RMS (AES standard) power handling and 94 dB sensitivity.

This model also incorporates Celestion’s DMM (Dual Magnet Motor) technology, where a secondary magnet is utilized to increase overall motor force (Bl) without the need for any increase in the size (and more importantly weight) of the magnet assembly.

The new CF1840JD is designed for reflex subwoofer applications, with a 4-inch/100mm multi-layer voice coil. It delivers 1,000 watts RMS (AES standard) and 96 dB sensitivity. Twin demodulation rings reduce flux modulation, further lowering electromagnetic distortion.

Both models feature BAV (Balanced Airflow Venting) to provide enhanced magnet assembly cooling, further enhancing performance by minimizing thermal compression.

All CF Series loudspeakers are designed using specialist FEA (Finite Element Analysis) modelling techniques, enabling Celestion’s development team to rapidly achieve genuine increases in performance, such as a highly symmetrical cone movement. This results in exceptionally low harmonic distortion and a more efficient performance.

Developed at Celestion’s headquarters in Ipswich, England, The CF series incorporates a unique and powerful industrial design, created in partnership with Allen Design Associates. More than a simple cosmetic makeover, this aesthetic is intrinsic to the performance of the loudspeaker itself.
