Celestion launches new small-format, coaxial drivers and weather-resistant, compact, low-profile driver range

Celestion, announced the launch of two new small-format, coaxial drivers and the AF weather-resistant, compact, low-profile drivers range, designed for use in compact line arrays, column speakers and compact single-speaker applications.

Cost Effective TFX Drivers Complement Existing FTX Series

The two new pressed steel chassis of the TFX0512 and TFX0615 provide a very cost effective complement to the company’s well-established FTX series of coaxial units, for applications including compact, fixed-install sound reinforcement and cinema audio. Both TFX drivers feature a Celestion ferrite motor driving the low frequency element. For HF reproduction, they feature a high sensitivity, 19mm/0.75inch (TFX0512) or 25mm/1.0inch (TFX0615) neodymium magnet element incorporating a silk diaphragm.

With neodymium having a stronger magnetic force than ferrite, this permits the high frequency element to be built with a much smaller magnet assembly than would be the case if ferrite were used. The resulting compact size of the HF unit enables it to be positioned inside the LF driver’s voice coil, at the exact point where the acoustic centres of both sources are ‘coincident’. The benefit of this is well-matched directivity and time alignment of the LF and HF signal, delivering maximum signal coherence for a more natural sounding reproduction.



“The launch of the TFX range is all about providing designers of sound reinforcement equipment with more options,” explains Celestion Marketing Director Ken Weller. “If you liked our coaxial drivers such as the FTX series, but ideally needed drivers that are more compact, more affordable, or both of the above, the TFX range provides a solution that fits your requirements.”

Ferrite Magnet AF Drivers Complement Existing AN Line Array Driver Range

The first models in the series consist of two lightweight full-range models, the three-inch (75mm) AF3010 and the four-inch (100mm) AF4010, the new driver range complements the company’s existing AN series of line array drivers.

“Our AN series drivers have been so well received by our customers that we wanted to offer the AF Series as an alternative, designed to reach a wider marketplace,” explains Ken Weller, Celestion Marketing Director.

The new lightweight (around 600g/20oz) AF series uses exceptionally cost-efficient materials, meaning that together with the existing AN drivers, customers now have a wider range of driver sizes and construction types to suit all design budgets.

The three-inch AF3010 is a 35W driver with sensitivity (@1W/1m) of 87dB, and with a frequency range of 120Hz to 19kHz. The larger AF4010 also delivers 35W, with a slightly higher sensitivity of 88dB and frequency range of 100Hz to 16kHz.
