Products of the HYDROGEN series match with the demands of highly sophisticated customers.
Amazing performance, great sound quality and high SPL whenever required.
The subwoofers have been developed to handle a huge amount of input power reaching extremely high bass levels, to be used successfully even under competition conditions.
A matching 2-way component speaker system and a number of MINI amplifiers with compact dimensions for limited installation space complete this famous GROUND ZERO line-up.
Not a huge surprise but a great honour, the performance of the GZ ULTRA A-2 charmed the members of the EISA, a group of international car audio trade journalists, right from the very first listening sessions that much that there was any doubt about the decision to award this amplifier as
“BEST PRODUCT – IN-CAR HIGH-END COMPONENT”
Only the best components ever have been considered good enough to find their way to the REFERENCE amplifier line-up.
Cooled by a high-quality copper-anodized aluminum heat sink, each model has been equipped with a slightly toned acrylic bottom allowing a glance on the selected components accurately arranged on the discreetly white illuminated and copper-plated double-layer pc board.
The 4-channel version has been awarded by the EISA organization as the world´s best in-car amplifier 2018/2019.

ULTRA speakers are designed for the most demanding music lover.
Carefully built by hand with the best materials and selected in pairs, they are delivered in fine wooden boxes.
The mid-bass driver ULTRA K-165 uses a high-tech fabric cone “Made in Germany” in conjunction with linear suspension and a narrow-tolerance copper voice coil with a linearized NEO motor. Built in a filigree aluminum basket for optimal air flow, these are the ingredients for outstanding neutrality and sound quality.
The tweeter ULTRA T-30 with its 30mm coated silk dome is characterized by a particularly low resonance frequency and extreme neutrality. The linearized NEO magnet system with the complex rear ventilation of the cone in the solid aluminum housing enables the wonderfully spatial and precise audio reproduction with an extremely wide frequency range.
REFERENCE speakers are designed for demanding high-end music lovers. Accurately hand built in Europe, selected in corresponding pairs and delivered in classy wooden boxes. Midbass and midrange speakers are made from hand-coated, pressed paper cones and hand-spooled copper voice coils, inserted into manually machined aluminum parts of the basket, forming the basis for outstanding high-end sound quality. The tweeter features a particularly low resonance frequency. The usable wide frequency range of the hand-coated silk dome thus enables astonishingly spatial and precise audio reproduction.
This exceptional subwoofer has been optimized to perform in small enclosures.
