You can't describe the system with a single group delay figure. Because there are multiple direct and reflected sound sources, some components will be shifted less than one wavelength, some greater. The interaction is complex, and can't be effectively corrected with delay or with electrical EQ. However, the use of several sound sources tends to average the amplitude response throughout the room, making the overall energy distribution more uniform.
