The TFX0515 is a 5″ diameter pressed steel chassis ferrite magnet coaxial speaker, representing a performance upgrade over the earlier TFX0512. With a larger 1.5″ voice coil, the speaker provides a 150W (AES standard) power rating with a 89dB LF sensitivity (96dB HF sensitivity).
It incorporates a silk dome tweeter and integrated HF waveguide to deliver a 80Hz to 20,000Hz frequency response. An external crossover is require to achieve this, detailed in the attached PDF.
