Very nice Sub! Tested and works great and sounds fantastic. The PDR-12 is the very definition of the 12" subwoofer. It features a single 12" long-throw woofer in a rear-ported cabinet that’s a little over 16"H x 14"W x 19"D. The PDR-12 weighs in at a respectable, but not exactly hefty, 41 pounds. On the back you’ll find an internal amplifier that produces 110W of continuous power and 330W of peak power. The PDR-12 also features auto on/off -- with an indicator on the bottom of the grille to let you know it really is on -- variable crossover frequency, and level control. Very nice used condition no major dings or scratches just minor signs of use. Please ask questions and thanks for 👀
