In my last DIY speaker setup in a fully treated room that was right on the verge of being to dead and sounded superb. I placed the mic at the MLP for REW and a HTS member tuned my DIY speakers. In my current room which is NOT fully treated, and is a huge concrete room with some room treatment panels, and some large rugs (nowhere near enough due to the 32' tall ceilings and open floor plan), I am not sure what the differences would be tuning one way vs the other. I know most people I know tune from 1 meter, but my rational on doing it last time was that if I tune from the MLP it would be more relevant (due to that is where my head is)...it def is easier as the mic stays in the same position and is just rotated toward the speaker.. Anyone here that can assist me in which way would be best in a live sounding room?
