Beveik iš niekur nieko "Ground Zero" pateikia naują viršutinę eilutę, kuri vis dar yra aukščiau už etaloninę seriją!

ULTRA - this is the name of the best components from Ground Zero from now on. Whoever thought that the previous Reference components would not be able to do more, will be proven wrong. Not only an over power amplifier, but also the matching speakers are at the start. At least partially and here in the editorial office still as a pre-series. Therefore, the woofer GZ ULTRA K-165 and the tweeter GZ ULTRA T-30 are visually not yet final. The finish of the front panel, grilles and basket will be changed again in the series, we have the final samples for approval of the series production. Our 16 woofer and tweeter will become a whole speaker series in the future. A midrange driver, probably 85 millimeters and of course a 10" subwoofer are already in development.
