With an almost evangelistic passion for in-car HiFi, the Elettromedia Group founded a sub-brand Hertz in 1998. The audio brand, named after Hertz, the discoverer of electromagnetic waves, shares his rigorous approach and innovative thinking, and in less than four years, it won the 2002 EISA award for Best Interior Speaker Set for its development of a neodymium magnet unit. After solving the system components, Hertz focused on optimizing the subwoofer driver for a long time, including the development of a forced cooling system, a V-diaphragm that ensures perfect cone symmetry, and an aluminum short-circuit ring that prevents low-frequency loss. The effort paid off, and it didn't take long for the Mille ML 2500 to win the 2007 CES Award for Innovative Design Engineering.
 
After many years, the MLK 1650.3 LEGEND has made another effort, and the MLK 1650.3 LEGEND manages the tweeter and woofer separately through two independent amplifiers, which is particularly harmonious with the dynamic atmosphere and timbre, even the most discerning ears will inevitably fall for it, and thus won the 2015~2016 EISA Best Interior Speaker System. Just one year later, the new ML 2500.3 LEGEND once again beat all competitors on the market and won the 2016~2017 EISA Best In-Car Subwoofer honor. "Constant innovation and precision construction have always been Hertz's key to success, with the V-cone® body, anti-resonance alloy suspension, and 100mm voice coil forming an unprecedented linear combination that accurately conveys the emotions of a live performance into the car," the organizing committee concludes in the product description.
