Which group delay looks best and why? Please explain a little...

Hi
There is something funny about those curves. Sound travels at the rate of about .883 ms per foot and so the curve suggests the 200 hz range is about 40-50ms behind the hf section which is much larger than the delay a normal crossover would produce. What kind of speakers are these and how were they measured?
Best,
Tom
Because of the large scale (100mS is like 113 feet of sound wave travel), I would guess this is a calculation from an in-room measurement, and dominated by the room's reverberation rather than the direct sound.
Those don't look like group delay charts.
What do they look like?
This is a typical subwoofer group delay chart.
Ah there's the problem my graph is full range not just the sub
