Celestion has announced the introduction of the new FTX range of common magnet motor coaxial loudspeakers, and they’ll be on display at the upcoming 2015 NAMM Show in Anaheim at booth 4674.
Coaxial loudspeakers offer a full-range frequency response in a single self-contained driver and by concentrically aligning low and high frequency drivers, act as more of a “single source” that can provide improvements in signal alignment and off-axis response when compared to a traditional two-way system.
Celestion’s FTX range of cast aluminum, ferrite magnet coaxial loudspeakers are available in 12-inch (305mm), 8-inch (200mm) and 6.5-inch (165mm) chassis diameters.
They offer combined LF and HF components 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 centers of the two drivers to be brought closer together, delivering further improvements in signal coherence and time alignment, for a more natural sounding audio reproduction.
The use of a single magnet assembly also means lighter weight and a more compact profile, compared to more conventional dual motor designs.
Each of these models has a polyimide film HF diaphragm, enabling them to provide greater high frequency power handling. Next-generation Sound Castle soft clamping assembly decreases diaphragm stress for further reduced distortion and even greater reliability of performance.
Both HF and LF voice coils are edge wound using lightweight copper or copper clad aluminium. Not only does this increase barrel stiffness, it enables a closer coil wire packing density, leading to improved cooling and increased motor strength.
Additional features include demodulation rings that minimize the effects of power compression, as well as reducing the harmonic and intermodulation distortion that is commonly associated with voice coil displacement.
