I've this subwoofer since nov last year. Was used in few movies, probably not more than thirty. The gain never passed half of the power. This is an outstanding subwoofer, in a compact size 19.75" (W) x 17.625" (H) x 15.875" (D) and with lots of power 1600w. The SuperSub XXL's guts include two 12-inch, long-throw, high-output active drivers and two 13x15-inch "quadratic planar infrasonic radiators" (i.e. rectangular passive radiators). On the marketing side says 10Hz but from the reviews the bass extension gets down to about 16 Hz, which is the approximate -10 dB point according to an average of several nearfield measurements. The reason to sell this subwoofer its because I need some financial support to fund one private project. I've the box and the extras. The subwoofer its in perfect conditions. Has the guarantee valid in any country, which is great. Let me know if you need more details.
