Default Subwoofer in phase ...with only one speaker

Hello everyone,

After I installed a single Rel subwoofer into my system I realized
that it would be in phase with one speaker and not with the other.

I explain: My room is just a bit more then 4000 cubic-feet, L shaped.
I set the subwoofer into the left corner behind the left speaker
(Unfortunately this is the only option I have). So, I measured the
frequency response of each front speakers with an real-time analyzer
and I found out that when the phase of the subwoofer is set to 0 the
right speaker's mid-bass frequencies decrease the output considerably.
When I switch the sub's phase to 180 the left speaker's mid bass
portion is sucked in. I checked the wiring, all matches red-to red,
black to black. I thought... maybe I should reverse the polarity of
one of the mains to even up with the sub, but that would screw up the
phase between the two mains. Is there any solution?
Is the distance between sub and mains the cause of this phase
'disparity"?

Any input would be greatly appreciated.
Thank you.
