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.
