Up for auction is a pair of Massive Audio GTX124R's. These are not to be confused with regular GTX series of subwoofers.  The regular GTX subs are a great series, but these are a step above. In a nutshell they are simply better constructed, and handle more power. This auction is starting at $1 with no reserve. Here is your opportunity to get a great sounding pair of speakers at a fraction of their retail price. As always good luck, and happy bidding!!!!
