It´s hardly possible to improve one of the best sounding amplifiers on the market. Nevertheless, GROUND ZERO selected some latest electronical parts and spent hours of listening to improve the parameters in detail! A new and improved pre-amp section, enhanced BIAS range and most of all a better Signal-to-Noise ratio deliver a clearly audible enhancement in Sound Quality of the SQ version.
There is now an optimized 2-way loudspeaker system especially for the Mercedes-Benz C- and E-Class as well as for the GLC. In addition to the midwoofer driver with a high-quality aluminum cone and a stable cast basket, it includes a specially adapted crossover for the sound quality 25 mm / 1” tweeter with coated silk dome. The system can be installed without any changes to the factory wiring and thus, if necessary, later also back again.
All you need for an efficient noise reduction of two doors within one package. The new PRO version not only includes 3 different types of damping materials, but in addition two sheets of GZDA 1200AL-GOLD, a pure aluminum plate leading to an increased effect of the overall damping.
All left-hand drive (LHD) Mercedes customers have been offered GROUND ZERO subwoofers to upgrade the OEM sound system already since last year. Now, the line-up has been extended by woofers for right-hand drive (RHD) models, too. The subwoofers are available separately for the driver´s and the passenger´s side.
High efficiency paired with good sound quality…that is the TITANIUM speaker line. For the new X generation GROUND ZERO added a completely new 20 mm / 0.79” silk dome tweeter to the component speaker systems of the line-up. This amazingly good sounding tweeter is available separately for individual sound upgrades of existing speaker systems. The package includes accessories for flush mount and angled surface housings.
While GZRW 30-D2 delivers already a bunch of low bass for every day music listening,
the new 15” version tops that performance by even more earth-shaking bass for all those who need “a little” bit more.
Finally, after a long evaluation period, GROUND ZERO launches the most powerful
mono subwoofer amplifier available on the market for every-day use.
GROUND ZERO improved the performance of the HYDROGEN series SPL subwoofers. The new XSPL generation comes with a completely new surround, developed for high excursion and outrageous SPL. Furthermore, the line-up includes not only the double 1-ohm models but double 2-ohms voice coil versions, too.
Loudspeakers of the COMPETITION series are characterized by a particularly high degree of efficiency and are therefore also ideally suited for ambitious projects. The new woofers and midrange drivers are available in standard sizes of 165, 200 and 250 mm. While the protective grilles are already included in the smaller models, GZCK 250XSPL Grill for the largest version of the line is available separately. Traditionally, these speakers are available single, one piece per package.
The new loudspeaker systems of the COMPETITION series meet the demand of many customers for a perfectly matched 2-way system for special purposes … with high power handling and a particularly high output level. The passive crossover, which is included in the 2-way systems with 165 mm / 6.5” or 200 mm / 8” midwoofer, offers the possibility to connect further midwoofers and tweeters for even higher levels and dynamics. The crossover is also available separately in pairs.
The successor of the very popular amplifier GZDSP 4.80AMP offers almost identical dimensions but some additional functions and has been improved sound-wise even further using high-quality components. In addition to the optical digital input, a coaxial is now available, too. Using the optional GZDSP REMOTE PRO-X remote control, all inputs can be selected, the user settings be recalled and both, the overall level and subwoofer level be adjusted.
The very popular 2-way speaker system of the TITANIUM series GZTC 165.2 is now also available as a 3-way version. Apart from a very flat 10 cm / 4” midrange driver with neodymium motor, there is also a perfectly matching 3-way crossover with level adjustment for the tweeter in the package. For full active operation, the set is available as an ACT version without the passive crossovers.
THE NEW “SOUND QUALITY” SYSTEMS OF THE RADIOACTIVE SERIES
TBy using a DSP and amplifiers for multiple channels, multi-way loudspeakers are increasingly used in so-called full-active operation. A passive crossover is not needed. That’s why the sound quality RADIOACTIVE loudspeaker systems are now available as ACT versions, too.

THE NEW “SOUND QUALITY” SYSTEMS OF THE RADIOACTIVE SERIES
The GZRC 165.3SQ from the Radioactive series is a 165mm 3-way component speaker system.
With the 3 ohm technology you get up to 25% more power from your amplifier and radio out. This, coupled with a peak efficiency of 90dB, allows for even the use of rather small amplifiers outstanding results. These and other benefits await you in the Radioactive series from Ground Zero.
The new GZTB 120F is a particularly space-saving subwoofer enclosure with a beveled side and the flat 12” subwoofer GZTW 12F from the TITANIUM series. Thanks to its modest dimensions, the enclosure can be used at cramped installation positions or in the trunk of vehicles with loading-through option for the rear seats.
The subwoofer grill of the GZPW 10SQ is now also available separately. In addition to the massive aluminum ring including both, a decorative ring with Ground Zero logo as well as the sturdy mesh grill with fixing ring.
The new GZCT 500IV-B is a high-performance compression tweeter with very high efficiency. The black anodized aluminum housing is provided with a thread, which allows installation in any desired installation depth.
The new GZPW 10SQ subwoofer has been specifically designed to meet the needs of audiophile listeners and fits well into a small sealed enclosure. The typical Ground Zero sound not only convinces discerning music lovers, but even bass freaks who wouldn’t expect this performance. The cone of the 25 cm / 10” subwoofer is made of anodized aluminum and completes the valued appearance. The delivery includes a sturdy mesh grill, which offers protection in every installation position.
The new BMW-specific 2-way speaker system offers an exceptionally good-sounding tweeter, whose frequency response was optimized for the original speaker positions. A coated silk dome provides in conjunction with the matching 4” midwoofer an impressive performance qualifying its name SQ +. The package contains a plug’n’play high-pass filter providing an even more precise and unadulterated playback when used without an additional amplifier. Of course, all connections are provided with the original plugs avoiding any change to the factory wiring.
With the NXP chips installed, the Hydrogen MINI amplifiers are among the most interference-free amplifiers on the market and are well prepared for everyday use in terms of features.
We are extending the series with a performance enhanced version of the “MINI ONE” with the “MINI ONE-K”.
