If two speakers are out of relative phase, the sound seems to be coming from everywhere (or nowhere in particular), but, usually not straight out of the speaker. But, an incorrectly wired speaker could be an issue. If the drivers are incorrectly wired in one speaker, this could damage imaging while not obviously being out of phase (I've seen speakers with such internal wiring issues).
Still, my bet is that it is a speaker placement issue. IT sometimes takes a whole lot of experimentation to find a good spot. I've seen a few rooms where a really good spot just did not seem to be available, but even there, persistence at least yielded the best of a bad situation.
