       | The information is useful, but rudimentary. The thing to remember
       | about phase in acoustic systems is that, as long as you're
       | driving your transducers (speakers) at the correct polarity (+/-)
       | vs. (-/+), you're probably good. Acoustic frequencies are low so
       | the lengths of acoustic waves are hundreds of meters long. Small
       | phase differences from a local transducer become irrelevant.
       | Phase differences between transducers distributed over a larger
       | area can be a concern, and can be automatically corrected for a
       | specific location with modern DSP/equalizers.
