While Celestion is legendary in the guitar and bass world, the British brand is equally distinguished in sound reinforcement. The CF series includes speakers designed for demanding sound systems, where mechanical robustness and consistent performance are paramount. The CF1840JD fits this lineage with a die-cast aluminum frame and architecture engineered to deliver the Celestion sound signature expected by professionals.
The CF1840JD is aimed at contractors, integrators, venues, and speaker manufacturers seeking a reliable 18-inch driver for low frequencies. It is particularly suitable for bass enclosures and sound reinforcement subwoofers, as well as high-power two-way systems requiring a solid foundation in the low end of the spectrum.
The die-cast aluminum frame ensures high rigidity of the basket, limiting deformation and promoting better mechanical endurance at high levels. Paired with a ferrite magnet, it provides appreciable thermal stability during prolonged use.
The 4-inch voice coil contributes to the CF1840JD's ability to handle high power while maintaining controlled response. With a sensitivity of 98 dB and a nominal impedance of 8 ohms, it integrates easily into many crossover and amplification architectures. Its useful frequency range from 30 Hz to 2.5 kHz makes it an excellent candidate to cover bass and low-mid frequencies in a sound reinforcement system.
