If you'd like to test the results of SubAligner, start by measuring something where the results will be obvious. I recommend a ground-plane measurement from a very close distance (~1m).

If that works, then try:
1. The recommended filters.
2. Moving farther away.
3. Speakers deployed at their usual height.
4. Microphone at head height.

Make sure you are doing the listening tests as well as measurements. I have found that when measuring indoors, the farther away you get the more difficult the measurements become to read. As reflections begin to dominate direct sound the phase trace goes FUBAR, but a listening test may still reveal differences, especially if you have been training your ears to hear the differences under previously more controlled circumstances.

Let me know what you discover!

I love to geek out about the physics of sound. This channel focuses on the growing opportunity for live sound engineers to improve their confidence and consistency through the understanding of the principles of sound system design and optimization. My goal is to make this channel upfront and honest about my success and failure, so you can learn from both.

I am always open to suggestions and feedback so please comment on this video or contact me through my site.
