Lightly used Paradigm Seismic 12 Subwoofer.  It was used in my media room for movies only so it hasn't seen a lot of use.  Works perfectly and gives a great deep base without being overly boomy.  Originally cost me over $1400!  The only reason I'm selling it is that we sold our house and the new house will not have a media room.  $580 cash locally in the Plano/Richardson area.  Will not ship due to weight because it would be outrageous.  Will trade for a comporable Glock 17 package.
