Overview

Celestion TFX0515 5" Coaxial Full-Range Professional Driver

Incorporating a number of performance improvements over the older TFX0512, including bigger LF and HF voice coils, the new TFX0515 driver also features a larger ferrite motor driving the low frequency element, delivering overall greater power handling.

For HF reproduction, the device features a high sensitivity, 1 inch silk dome tweeter, driven by a highly compact neodymium magnet motor. With neodymium having a stronger magnetic force than ferrite, this permits the high frequency element to be much smaller 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 centers 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 new TFX driver emphasizes Celestion’s commitment to delivering a wide range of high-quality solutions for sound reinforcement applications that demand a full-range point source solution. They further underscore the company as the world’s number one supplier of branded coaxial transducers.
