The Mille line is enhanced with systems, coaxials and the PRO components, dedicated to the enthusiasts yearning for the authentic Hertz Mille listening experience.

In 1998 Elettromedia (Italian manufacturer of consumer audio products since 1979) creates the Hertz brand, giving voice to its amplifiers and becoming a world leader in the loudspeakers marketplace. Hertz quickly introduces important innovations in the drivers design technology, confirming creativity as a key strategic asset for Elettromedia.

In 2006 Hertz already occupies an established position worldwide among car audio brands and presents the Hi-Power line of amplifiers to the many fans who ask for entirely Hertz audio systems.

Since its launch, the Hertz brand represents many different kinds of high end mobile audio products, including amplifiers, speakers and subwoofers.
