Hey, I've got a 12" Directed Audio Studio Series 12" subwoofer in a ported box, great sub, won the CES creative award a few years back for great overall performance (Massive output AND sound quality) I had 700 watts on this thing and it absolutely loved it, sub itself is in perfect flawless condition, no marks or dents on the cone or surround. Comes with a 1.6 cu foot carpeted ported box tuned to 37 Hz and the grill that is pictured. Willing to meet and allow you to demo it if you've got an amp hooked up, you won't be disappointed. Thanks!
