Hifonics ZXT18D2

For over 35 years, HiFonics has stood for EXTREME performance and superlatives. Everyone knows: HiFonics represents power, performance, and high-impact sound. To complement the new “OVER” amplifiers from the ZEUS EXTREME ZXT series, boasting up to 13,000 watts RMS, the matching ZEUS EXTREME ZXT subwoofers are now available. A particularly striking feature is the triple magnet, the same size in all models, protected by a blue boot. Its substantial ferrite rings alone, even without the chrome-plated steel pole plates, weigh in at a hefty 8.5 kg.

The newly developed “Reinforced-Structure-Array” surrounds, reinforced with vertical elements, also hint at the impressive excursion capabilities of the carbon-reinforced cones. These cones remain incredibly rigid and, thanks to their triple-layer sandwich construction, are comparatively lightweight. To ensure the diaphragms can utilize their full excursion, they are guided by triple Nomex spiders, acting like rails. This guarantees that the diaphragms won’t bind, even under extreme power.

The Zeus subwoofers are also exceptionally well-equipped thermally: The 10-inch woofer already features 76 mm voice coils, while the 12-inch model and larger boast a massive 100 mm voice coil. With an incredible 58 mm winding height, the diaphragms can achieve a linear excursion of +/- 23 mm. The voice coil is made of special pi-CCAR flat wire, an aluminum flat wire with a copper sheath, which saves weight and is also heat-resistant up to 240 degrees Celsius. All these features impressively demonstrate the exceptional quality of the woofers. Anyone looking for the ultimate high-output subwoofers simply cannot ignore the ZEUS EXTREME ZXT series.
