I am the original owner of a PSB Subsonic 3 powered subwoofer. It has a 12" driver with a 180w amp. It is a front firing design with two, vertically aligned ports on the back next to the amp plate. The finish is similar to the Def. Tech. Supercubes: Black grille sock wrapping around all four sides with a piano-gloss black top plate. It has black plastic feet rather than spikes. condition is 9/10. It operates flawlessly. I have it EQ'd with a BFD and am getting +/-3db from 25-80hz. Physically it is 16"w x 16"d x approx. 17" tall. Originally $800. Have owned it about 9 years. Do not have original box, but I do have the manual. It is used for music/movies, about 50/50. It has never been abused and never been moved. Still rattles the windows and doors! I have upgraditis, so am selling it. Will put funds from sale into new unit. If you are looking for a "steal", you found it: $150+ shipping! I'm in the Cleveland, OH area and would prefer local sale, but will ship if needed.
