Wondering if there is any positive results for going 180 out of phase with the door mids/tweets for those that don't have a fully active system?

One thing that I have found is that I can get the most spl out of each sides underseat/mid combo playing a 200 hz sine wave when the driver underseat is 67.5 deg out of phase and the passenger underseat is 22.5 out of phase. The helix dsp allows these incremental phase adjustments.
