I hope that the answer to this question is not blindingly obvious, but I have not seen it discussed before and have been unable to resolve it by myself 
My dual manifold IB's are located in the front wall of my room, about 6' behind my main speakers.
The open baffle main speakers have a 15" coaxial driver which is run full range, and a 15" bass augmentation driver covering about 80Hz downwards.
The IB is crossed at about 80 Hz as well.
Therefore it is possible that at some frequencies there is output from all three sources.
With all drivers in phase, it would seem to me that the rear wave from the OB's would be out of phase with the IB and could induce some cancellation
Is my thought process correct?
Thanks,
Jim.
