Tweaking Your Speaker Placement

@tony1954 

Once the speakers are correctly placed in the room (i.e. they couple optimally), any slight movement has an easily perceptible sonic effect.

Since optimising speaker placement is, obviously, room dependent, I imagine we shouldn't take someone else's 1/8th move too seriously (or 1/16th for that matter)

After adding Stack Audio footers, tweaking my speaker placement was easy. Isoacoustics footers work great, but a pain to play with placement. 

My speakers weigh around 130# and are on Gaia ones. In the past I’ve used butcher blocks and found they helped a bit, but when I went to granite, things just came together. With my current speakers, the tweeters are higher and don’t have the same dispersion, so I can’t use the granite anymore. 
Oh and furniture sliders are a must.  Whether under the granite or just under the Gaia’s.

Jim Smith explains exactly how to setup, measure and move the speakers in small increments in his book Get Better Sound

I am certainly no expert. Based on your follow up comments, I assume, you must be attempting to tweak the speaker’s position. In other words, you have found the sweet spot. You are hearing a difference in sound that you have never heard before and like what you’re hearing. If not, I would only use a 1/8 inch adjustment on the tilt not changing the distance from the wall, toe in etc in the beginning. Hope you are making progress.
