Celestion remodels TFX coaxial

Designed for sound reinforcement applications that demand a full-range point source solution, Celestion has introduced an updated version of the TFX0515 5-inch ferrite magnet coaxial driver. With a rigid pressed steel chassis and 1.5-inch diameter polyimide voice coil, the redesigned TFX0515 incorporates larger LF and HF voice coils together with a larger ferrite motor for driving the LF element and improving 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 HF element to be smaller in size. 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, reportedly delivering maximum signal coherence for a more natural-sounding reproduction.
