Gotta say my first dip into FR+sub test of parallel vs series x/o, first order, is almost night and day, like going from conical to hypereliptical on a phono cartridge. Same pieces reconfigured, but the result is as if the parallel connection included a bonus scrap of heavy carpet in front of the full range. It lead to a few hours of vinyl spinning. I just sat there, loving the non-graphed detail.
