TRIAD MINI/8 SUB STANDALONE IN-CEILING 8" 8-OHM SUBWOOFER IN BLACK FINISH 51615-4080-3. This is a brand new, open box subwoofer that has never been used and was only opened for the photos. There is one tiny tiny surface mark on the back of the enclosure from when it was removed that we'll show in the photos, but it's super insignificant and otherwise brand new in perfect condition. It works perfectly. It comes with everything shown. These are normally $2500. This is your chance to save big-time so don't miss out!!
