Is it safe to say that if the sub is in the front of the room, very close to the front left speaker, that the phase is MOST LIKELY best at zero? I figure that since all speakers are on the same plane, the bass waves should not be canceling out. I know there are exceptions, and I am happy with the quality of my bass (SVS 20-39PC), but I have a lot of time in my commute to think. I know the common wisdom is to play a bassy track over and over while adjusting the phase, and listening for the best bass, but is there any way to do this objectively, with an SPL meter? The speaker level tones are of no use, since only the sub is playing, there is no cancellation. Others worry about their child's education, I worry about this... Any thoughts?
