Which is the right Subwoofer Phase?

Hello,
I have a Rel Stadium III positioned on the left corner next to one of
the two front speakers, Vienna Acoustics Mahler. I have set the High
Level Crossover to 27Hz. I am still puzzled by the subwoofer phase
settings. I checked with a digital SPL meter in conjunction with Rives
test CD 2. Whet I set the phase to 0, the sub outputs more sound at
32hz, (93 db) 40hz (95db) and less at 25hz(80hz) and 20hz(77db). The
contrary happens when I switch phase to 180. I get higher output level
at 20hz (83db) and 25hz (80db), less at 32hz (88db) and 40hz (84db).
In few words, depending from the test tone I play I get audible
different results, as to say phase 180 setting and test tone 25Hz or
less would be fuller then 0. With phase set at 0 and test tone played
at 32hz or even 40hz would be audibly fuller.
Because It appears that phase set to 180 phase would flatten the low
region of the sound would in practical terms be the best choice for me
since my room interaction produces a huge peak right at 32hz and 40hz.
But my question is: theoretically which setting would be the ideal?
Please share your expertise.
Thank you.

lives a bloody misary!!!!!!!!
