Summed Low Frequency Responses

When all door loudspeakers are excited together, in phase without filtering, the response at each listener location appears to have consistent characteristics between the model and the experimental data.  The front driver and passenger locations seem to be worse than the rear seats for bass response.  The rear side seats are around 5dB louder from 100Hz to 200Hz than the other seating locations.  The rear mid seat location also experiences a dip at ~200Hz and peaked response at 300Hz.

Despite differences in the individual driver responses at each listener location, the summed system response appears to report similar characteristics.
