Dear @hshifi : I understand your need too and I know very well the well regarded JL and Rel subs that hmore marketing that realities. What am I saying with realities?, example the JL THD is over 5% against the 0.5% in the Velodyne and Rel is not way better than JL in that very critical regards. So you have land down there to improve MUSIC and HT enjoyment the better.
