You asked: " can you explain option 2 betterZ?"
Not sure, but I think you're looking for a link to the Audio Kinesis Debra system. I would not use "DBA" on google searches. This is just an acronym I created for "Distributed Bass Array" that I don't believe is in wide use by others. Google "Distributed Bass Array" and you'll get more relevant info like Dr. Geddes's research and James Romeyn's Debra system that I own. Here's the link for the Debra:
