REL S/3 Subwoofer (Pair)

I have a pair of beautiful REL S/3 subwoofers for sale.  I am the original owner and purchased them new from authorized dealer.  I am asking $1188 each or $2150 for the pair. They come from a smoke and child free home.  They have only been in a 2 channel high end system and no home theater. I have them tuned such that they supply deep base and atmosphere to the music. They are not apparent unless you unplug them.  That is when you notice the lack of deep base and a collapsing of the soundstage. They work perfectly and are in very good to excellent condition.  There are no dings, dents or noticeable scratches visible to me.  I would like a local pick up or will deliver within 100 miles or so of the Dallas area.  I am only selling to upgrade to the carbon model.  This is not the Sho model. Once you have had a pair of REL subs in your system, you will not want to be without them. The reviews are spectacular. I have original packing, cables, and owner's manual. 
From the Absolute Sound:  "While a singer-songwriter might seem far removed from subwoofer-land, the REL’s underpinning creates better stereo separation, more of a sense of a live performance, and instruments precisely located within that stage. 

So far, this could apply equally to almost any correctly set-up REL subwoofer produced in the last 25 years. What the S/3 additionally provides is an even faster transient response, which frees up those middle and upper registers still further. While not a substitute for room acoustic treatment, the S/3 works like an active bass trap, but can also provide that bass depth needed when playing something like the ‘operatic’ version of West Side Story [DG], to best render all those foot stomps and stage directions. This is a tough test for a subwoofer, because it requires great depth and great speed, and the S/3 does both well. 

Although it can happily shake the walls every bit as much as its R328 predecessor, this is also a subtle and deft device".
