     The 25TF tweeter has incredibly linear frequency response characteristics, high power handling capability while generating ultra low harmonic distortion artifacts.

 

The 25TF Dome utilizes REDCATT in-house unique titanium coating technology. Nitride is extremely hard ceramic material. We deposit the nitride from both sides of the titanium dome. The coated dome has dramatically improved flexural rigidity (aka stiffness), compared to the pure titanium dome. The coating has dramatic effect onto the distortion artifacts. The 3rd harmonic distortion stays bellow 0.05% in the working range. Extended high frequency response without major dome breakup modes and improved transient response are the other positive effects of REDCATT Titanium-Nitride Domes.

 

The 25TF has implemented FEM tuned rear resonant chamber. The chamber is improving the tweeter behavior at low frequencies and further lowering the harmonic distortion. All tweeter parts are bonded together using state of the art high temperature adhesives. Metal parts in the tweeter assembly are coated for extreme weatherization protection.
