The HORIZON HZ loudspeaker series from ESX offers a perfect price/performance ratio and sets the bar in this price category enormously high. HZ speakers stand for quality, design and performance alike. An ultra-stiff polypropylene cone ensures accurate and clean deflections even at permanently high levels. The powerful magnetic driver of the loudspeakers is optimally protected with a strong rubber boot and sits firmly on a reinforced low-resonance steel basket. Nice looking discreet protection grille match perfectly to each system. The HORIZON HZ component systems and the large Coax/Triax models own a very high efficiency voice coil thanks to their 3 Ω impedance.
