HK Audio PREMIUM PR:O 118 SUB D2 Active Subwoofer
The PREMIUM PR:O 118 SUB D2 is an active 18-inch bass-reflex subwoofer built to be the low end of a portable PA, from a simple 2.1 setup up to a full stack. Class D power delivers 1,200 W peak with a selectable crossover from 75 to 150 Hz, and response extends down to 36 Hz. Its integrated system crossover lets mid/high tops connect directly, without needing an independent filter box.
The MDF cabinet is finished in jet black acrylic enamel behind a steel grille with acoustic foam backing, and includes subsonic filtering and peak limiting for driver protection. Connections cover two XLR/jack combo inputs, two XLR mid/high L/R outputs plus two XLR thru outputs, and a single IEC power inlet. It mounts on an M20 pole with wheel-assembly preparation and two MultiGrip carrying handles, weighing 87.7 pounds.
