Lately, GROUND ZERO introduced the new IRIDIUM series component loudspeakers with a particularly shaped HQPP cone with 3-D honeycomb structure. Expanding the line-up for the fans of SPL levels, the GZ engineers created a high-power capable component speaker system including the high-roll IRIDIUM GZIK 165SPL midwoofer (available separately, as well) and combined it with the GZCT 25M tweeter known from the COMPETITION line. Pointing out its main purpose, the components have been highlighted with yellow color accents, letting everyone know about the GZ SPL affiliation.

For some years customers were missing matching loudspeaker components and systems belonging to the GROUND ZERO HYDROGEN series to be combined with its amplifiers and subwoofers. Based on the aluminum cast basket known from the URANIUM series midwoofer, the engineers have realized a powerful 6.5” midwoofer with a strong ferrite motor and a generously dimensioned CCA voice coil. In combination with the brand-new vented silk dome tweeter GZHT 25S equipped with a coupled chamber and a 2-way passive crossover, the new HYDROGEN series GZHC 165.2 2-way system is born. The loudspeakers are available, separately for active setups, as well.
