I haven't followed all of the million responses, but in my opinion I'd get multiple subs in a heartbeat over one sub that digs deep. Running 2 subs to me has a huge benefit over just one, just a 'wider' stage 'easier' to get a more consistent spl at multiple sitting positions. It may not dig as low as we would all like, but one thing for sure (you all HAVE to agree with me) bass is not cheap. I'll take 2,3 or 4 'decent' subs over one single beast any day.
