History

Ground Zero Audio History

The Rise of the GROUND ZERO Company

GROUND ZERO has been founded back in 1995 by Karl Felix Lautner distributing
car audio products “Made in USA” and introduced the revolutionary subwoofers of
GZ Engineering USA to the European market in 1997. The following years, the German Company took over the European trademark rights of “GROUND ZERO” and started developing market specific products. Finally, 2003 the GROUND ZERO GmbH took over all global trademarks from the discontinued US company and expanded the distribution to customers worldwide. Today, more than 400 sophisticated audio products developed and designed at the GROUND ZERO in-house engineering department are available in more than 82 countries globally.

Ensuring Superior Quality of GROUND ZERO Products

The GROUND ZERO product range includes speakers, subwoofers, amplifiers and further digital audio equipment for enthusiastic customers. Satisfying high demands and quality, Ground Zero carefully monitors every step of the production starting at the development using top-notch tools and highly accurate measurement equipment such as the laser controlled KLIPPEL® system to optimize every detail. Precise amplifier measurement equipment by Audio Precision® results in power ratings corresponding to the acknowledged CEA 2006-A standard. Without exceptions, every single product is evaluated by extensive testing and quality control prior to its final production release and market launch.

On the Winner´s Side with GROUND ZERO

Many international car audio journals confirm the highest product quality impressing even sophisticated customers. However, the most convincing evidence is provided by the huge amount of GROUND ZERO equipped cars worldwide. With an outstanding audio performance, they succeed to be part of the winner´s circle of European and World SQ and SPL Championships every season.

Listening to music can be emotional, impressive, relaxing or enjoyable. At that, it doesn´t really matter what kind of music is the personal favorite, whether it´s Instrumental, Jazz, Electro, Latin, Classic, Rock or any other music direction. However, audio reproduction quality at each desired volume is elementary. Some music styles require higher levels while others prefer the soft tones.
GROUND ZERO considers all the different wishes of customers during the development of new products. Along with this, the target is to create the most realistic sound, to transfer the soul of the music and the intention of the performer. Summarized to one phrase: RESPECT THE MUSIC!
