The Dieci Line represents a new performance landmark in its category. Hertz aimed at obtaining high efficiency, maximum tonal quality and high grade tonal accuracy. The speaker cones and voice coil formers are made of a special natural paper mixture. Foam surrounds and cotton spiders ensure mechanical reliability and optimal control even under high excursion conditions. The large motor allows tight control of the loudspeaker moving assembly for tight, dynamic output. The Dieci line is the perfect speaker choice for factory OEM upgrades, direct head power or with high quality amplifiers.
