Group delay in subwoofers

I understand the phenomenon of group delay when subwoofers are connected to a preamp and that they need to be placed approximately 8 ft closer to the listener than the mains.  Is this also the case when connecting a sub through the speaker level inputs from an amplifier or is group delay much less of an issue in this configuration?

I would think connection via the speaker terminals should have no issue with delay, but I am not an EE.
Perhaps Almarg will help. If anyone knows about this stuff, it's him.
