  • News – HYDROGEN Loudspeakers January 26, 2022 by groundzero

    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.

  • News – PLUTONIUM GZPF 40SQX January 25, 2022 by groundzero

    Even high-quality tweeters are hardly capable of reproducing frequencies below 2000 Hz clearly and without distortion without accepting a limitation regarding the maximum output level. The sensitive mid-range must therefore usually be processed by a separate midrange loudspeaker. Due to the low resonance frequency of 440 Hz, the GZPF 40SQX can be used in full-active mode with the high-pass set to a frequency of 900 Hz even at higher levels and offers an extraordinarily clear and realistic sound performance as well as a detailed stage image thanks to phase-correct reproduction. With its small dimensions, the solid and polished stainless-steel housing can be installed at positions intended for tweeters.
