UK - Celestion has announced that the popular TFX0412 4” ferrite magnet coaxial driver is now available for individual purchase through retailers. With a rigid pressed steel chassis, the TFX0412 is a fully combined LF loudspeaker and HF compression driver that provides a very cost-effective solution for a variety of applications requiring compact, discreet sound reinforcement.
The TFX0412 features 1.25” diameter LF and 1” diameter HF copper clad aluminium voice coils powered by a common magnet motor assembly, where the same magnet is used for both the LF and HF elements. This enables the voice coils and hence the acoustic centres of the two transducers to be brought as close together as possible, delivering further improvements in signal coherence and time alignment, for a more natural sounding audio reproduction.
With the delivery of both low- and high-frequency signals from the same chassis, the TFX0412 offers a combined frequency response of 90 Hz to 20,000 Hz (a crossover is required).
The single magnet assembly also offers the advantages of a lighter weight, and a more compact profile compared to more conventional dual motor coaxial designs, enabling the speaker to be used in applications where space is at a premium.
The TFX0412 features a polyimide film HF diaphragm, enabling it to provide greater high-frequency power handling. Celestion’s Sound Castle soft clamping assembly decreases operational stress on the diaphragm, for ‘further reduced distortion and even greater reliability of performance’.
Also included is a demodulation ring that minimises the effects of power compression, as well as substantially reducing the harmonic and intermodulation distortion that is commonly associated with voice coil displacement.
