Hertz Mille MP 25.3 PRO Tetolon Fiber Soft Dome Tweeter 25mm (Pair)

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.

Thanks to its “Center Tuning Duct”, positioned in the center of the powerful Neodymium magnetic circuit, exchange of air between the dome and rear load chamber is ensured, fine-tuning the acoustics to perfection. The resulting very low resonance frequency is also functional for the woofer crossover point, elevating the sound stage.
