Titanium Driver D405Ti


Where to buy

This Selenium Loudspeakers driver features a 2” (50 mm) exit compression driver for high sensitivity, low distortion and smooth extended frequency response applications. Its pure titanium diaphragm was especially designed based on the extremely light and structurally strong snowflake crystal. That leads the D405TI driver to deliver high performance, high quality and high value for the pinnacle in sound reinforcement applications. It combines a stable structure for mid-frequency reproduction and a low mass that enables high frequency reproduction virtually linear to 18 kHz.

Its construction features include:

  • Ferrofluid (Ferrosound ) loaded gap reducing heat build-up and offering consistent results over long-term demanding concert usage;

  • Voice coil is made of high temperature wire wound on Kapton former to withstand high operating temperatures;

  • Injected plastic housing;

  • Precisely engineered diaphragm structure and alignment mechanism allows for easy, reliable and cost effective repair in case of diaphragm failure. If you are not willing to make the repairs, International Audio is the authorized repair center for the USA.
