That's not being fair as the above is trying to have it both ways. Cancellation is cancellation and removed cancellation, no matter what the phenomenon is that removes the cancellation, is still removed cancellation.
Once one is set up to measure their room's acoustics, it costs nothing but valueless time and enhances the play time experience and harms nothing in the process to twist and play with the subwoofer's potentiometers; measuring in the process, to the good or bad, how small parametric changes interact with a rooms acoustics. Experiment, live, play, enjoy.
What I don't understand is why some folks here are so adverse to measuring how small parametric setting changes affect acoustic measurements when doing so costs and harms nothing.
My recommendation, one should set their measuring gear up and play for a few days with subwoofer placement and parametric settings. And in doing so see first hand how small subwoofer placement changes and parametric setting changes affects both dips and nulls. Doing so doesn't hurt anything and costs nothing. It's all about adult playtime and in doing so will help one better understand how their subwoofer's output interacts with their room's acoustics.
I am fortunate to have a dedicated media room, and an understanding wife (to a point...)
I have an understanding wife.....as long as it meets with her approval, she's understanding.
