When you go to a musical event, you may sit toward the front, back, sides......people may be shuffeling programs, coughing, moving about. I use the classic T , a Bosch laser, and a/v receiver room correction followed by some manual alteration. My ral thought though is dont obsess too much and enjoy the music.
Speaker Positioning
I know from speaker position is critical in achieving the best results from a given system. Is there a dynamic way to measure placement of each speaker to make certain they are the exact same distances from back/side wall, cabinets, seating, etc. beyond a measuring tape and listening to the results? Seems to me if minor differences pay large returns, you could be tinkering with this a long time. Thanks for the indulgence.
