Making its debut at NAMM 2023 is Celestion’s new TFX0412 4" ferrite magnet coaxial driver. With a rigid pressed steel chassis, 1.25" diameter (LF) / 1" diameter (HF) copper clad aluminum voice coil, the TFX0412 provides a very cost-effective addition to the company’s well-established series of coaxial units, for applications requiring compact, discreet sound reinforcement such as ceiling speakers and cinema audio.
The TFX0412 features a fully combined LF loudspeaker and HF compression driver that are powered by a common magnet motor assembly, with the same magnet used for both the LF and HF elements. This enables the voice coils and hence the acoustic centers 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 90Hz to 20,000Hz (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 next-generation Sound Castle soft clamping assembly decreases operational stress on the diaphragm, for further reduced distortion and even greater reliability of performance.
Both HF and LF voice coils are edge wound using copper clad aluminum. Not only does this increase voice coil barrel stiffness for more accurate sound reproduction; it enables a closer coil wire packing density, leading to improved cooling and increased motor strength. Also included is a demodulation ring that minimizes the effects of power compression, as well as substantially reducing the harmonic and intermodulation distortion that is commonly associated with voice coil displacement.
"The TFX0412 delivers the technology and performance level of our highly successful FTX range in a more lightweight and affordable pressed steel form factor," comments Celestion Marketing Manager Ken Weller. "This latest addition to an expanding range of high-performance coaxial drivers is a reflection of Celestion’s commitment to providing sound reinforcement equipment designers with new options."
Celestion CDX1-1412 and CF1025BMB
Announced in 2021, and already characterized in Vance Dickason's Test Bench, the CDX1-1412 is a 1" exit, neodymium magnet high frequency compression driver. The unit’s ultra-compact size makes it ideal for small two-way cabinet designs and other highly portable applications, at a very attractive price point.
The latest of Celestion’s high frequency compression drivers, the CDX1-1412 is extremely compact for a 1" exit compression driver, enabling it to be fitted into small cabinets where space is critical, or to be used with multiple driver horns. The unit features plenty of output for a driver this size: 35W (AES standard), 70W (Continuous) power rating, and 107dB sensitivity across a 1500 to 20kHz frequency band.
Introduced in 2022, and a finalist for outstanding technical achievement in the 2023 NAMM TEC Awards, Celestion’s CF1025BMB 10-inch diameter ferrite magnet, cast aluminum chassis professional audio loudspeaker is well-suited to both bass and mid-bass applications and particularly excels as a bass unit in compact subwoofer applications.
The CF1025BMB features a 2.5" multi-layer voice coil providing 300W (AES standard) power handling and 92.5dB sensitivity with an output frequency range of 45Hz to 5000Hz. The elastomer surround enables a longer Xmax compared to a conventional 10” mid-bass speaker, allowing the CF1025BMB to better reproduce lower frequencies. This makes the driver a natural solution for discreet, compact subwoofer applications. However, it also performs very smoothly up to 2kHz, making the CF1025BMB a superb option for 2-way designs with the added advantage of exceptional low frequency performance.
Developed at Celestion’s headquarters in Ipswich, England, these products were designed using specialist in-house software deploying FEA (Finite Element Analysis) modeling techniques, enabling the Celestion engineering team rapidly to achieve genuine increases in performance, that translate into greater product longevity, and exceptionally low distortion.
These powerful PA products are the latest examples of Celestion’s continuing commitment to delivering a wide range of high-quality solutions for sound reinforcement and professional audio applications.
