About the Hertz MP 25.3
Smooth Hertz highs
Smooth Hertz highs
Hertz's Mille PRO Series tweeters serve up delicious detail, thanks to a 1-3/16" Tetolon fiber dome driven by a neodymium magnet. A special Center Tuning Duct helps extend the lower end of the frequency range for a smoother sound and less distortion.
