From 25% correction to 7%

I wanted proof, not a feeling. So I ran my room correction twice, once with my acoustic treatment off the walls and once with it back on: 25% the first time, 7% the second.

That is a colossal difference, and all I had really done was play with the speaker positions and install a few thousand dollars or less of acoustic panels. The machine was not correcting my speakers or my electronics. It was correcting my room, and the panels had already done most of its job.

This is how I read that number. Every percentage point a processor has to correct is a percentage point the room adds before your speakers get a fair hearing. When the number collapses, the room has stopped fighting the system.

You do not need my device to see the same story, trust me. A microphone at your seat and free measurement software will show you the before and the after, panel by panel. My expensive box only confirmed what a free tool would have told me.

Measure with the panels down, then with them up. The gap is the most honest number this hobby will ever give you.
