The Rel is old tech. Check the the Velodyne website and read about seemless intergration. It has a built in computerized room correction that is diplayed on screen. First do the sweeps from 15 to 200htz and see what your main speakers are doing in the room. Second,bump up the volume on the Velodyne sub. until it is close to where you want it. Third use the EQ to flatten out the room responce.
This is nothing like any other sub.
