High Performance 1" Tweeter featuring a tuned and damped double rear chamber, giving a low resonant frequency of just 850 Hz. The voice coil / gap is filled with low damping ferrofluid for cooling / thermal stability without affecting the transient response; the voice coil is terminated with tinsel braided leads.
Used in PMC models: FB1, TB1, TB1S, TB2, TB2S, DB1, DB1S. Also suits some early ATC designs.
This tweeter directly replaces the Vifa D27TG-35-06 and is manufactured in Scandinavia. Capable of excellent results and great value.
