The CI-HV18 is an extremely powerful passive or active version (500 watt amplifier) subwoofer capable of thunderous output and gut wrenching impact. At a staggering 120 dB @ 6M max output, it’s capable of producing bass almost as loud as a 747 taking off at 300 yards away!

Key to its performance is a 2000 W RMS 18″, ultra-long throw, internal bass driver used in a sophisticated high-velocity tuned loading system. Two flared Aero Vents (1-6″ and 1-4″) produce extremely intense pressure waves that energize the surrounding room environment. Bass output rivals or surpasses that of subwoofers 3 to 4 times its size. Available in residential, commercial and outdoor application finishes.
