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.

Good luck having your head consistently in the same spot, to the mm every time you listen.
@audio2design, more critical is ear placement on ones head.  I had mine adjusted to be perfectly equidistant from a center line I had tattooed down the center of my face.

Once I got my ears properly placed, the imaging really snapped into focus.  Highly recommended but as always, ymmv.
Hey Larry, Merry Christmas!
Wheres Oldhvymec??  He’d be proud...  I’m up 2 positive remarks today.  I think Im a changed Man 😝

As for speaker placement, I just switched my rig from the short wall to the long wall.  Pulled the speakers a ridiculous distance away from the front wall in order to smooth out the bass as much as possible.  Its a nearfield setup now which allows me to hear more detail.  I still have a great soundstage.  Nice and wide and deep too.  
Speaker placement can have huge effects on a speakers performance and its free so why not try a few different locations for fun!
