The ZXS subwoofers from Hifonics perform excellently in very small, closed enclosures as well as in slightly larger bass reflex systems. The woofers use made paper cones with double-stitched surrounds, which have also been impregnated with a special coating. Optimized in this way, they can easily withstand the high pressure in small housings. The power of the ZEUS woofers can also be seen visually: large double magnets with pole core holes and ventilation channels signal pure power. Matching this, 2 + 2 Ohm dual voice coils are used.
