The IV6-118S is a high power 1 x 18″ compact, direct-radiating subwoofer designed to complement the full range IV6-1122 elements in any array configuration with deep, impactful low frequency support. Large, balanced ports provide optimal enclosure tuning and even air pressure distribution to the driver cone, reducing distortion and extending system longevity. A FEA-optimized ferrite motor with long linear excursion capabilities provides deep bass response for the enclosure’s size. With 800W @ 8 Ohms of continuous power handling (80V), the IV6-118S subwoofer can be conveniently driven by the same size power amplifier as the IV6-1122 full-range array elements.
