Tweaking Your Speaker Placement

"Depending on the speakers an 1/8” move in the right way can have a significant impact."

What I am curious about is how one can verifiably move a speaker exactly 1/8th of an inch? My speakers on stands weigh about 60 pounds each and being bookshelf speakers, they are a little top heavy. They are also on IsoAcoustic Gaia's, which don't really slide too well.

How do you do it?

Easy I use one of these. https://www.amazon.com/BOSCH-GLM100-23-Measure-Backlit-Display/dp/B0C76CPGC7/ref=mp_s_a_1_3?crid=2WDR657NDUOSU&dib=eyJ2IjoiMSJ9.rG5aOOoS3-JqO3BDybBQ3sS2K4rDOEnWggY2QeNhLMCg3VsIebM_aQQFFroRB_hgFD26MwCNdrMDE-qmmaH6CfdTkcHmm0z2eyFFXwU78oZN8beB0WjKOmQW0LIBlbe2Gc6xKS0ymILQtPGF64nlMThu9qgqRospN-dZ48UYbV7MvPpvVyA_gFMuwdfdXuIjWxrc4xdufC0AUBbqCx98XQ.as63VkuJwsaT9UU2_wxcetyFj9cy9nZ6DXc93h4Ntdw&dib_tag=se&keywords=digital+measuring+tape+with+laser+dewalt&qid=1736207966&sprefix=digital+meaduring,aps,127&sr=8-3

I used to own planar speaker... those tend to be the ones that are that sensitive to really minor adjustments. I use a laser measurer... and then the sound can literally snap into focus. 

Dynamic speakers tend to be less sensitive.

Man I HATED those IsoAcoustics - made it impossible to slightly adjust speakers lol. Herbie's Gliders are great for sliding speakers in a very controlled, precise fashion. However, I'm not one of those who believes things need to be precise down to the micron.

Tell me. What’s the significance of adjusting speaker placement in exact increments of 1/8 of an inch? I’ve never heard of such a thing. Maybe it’s just a personal fetish. In over 40 years in high end audio, I’ve been pretty successful at optimizing speaker placement in my rooms by using, simple, good old fashioned, Kentucky windage lol. Happy listening.

An 1/8 of an inch -- does that mean you have to keep your head in a vice?

Such precise placement of loudspeaker and listener should not effect tonality or dynamics, but it might provide some soundstage/imaging info on some specific recordings.  Possibly similar to adjusting VTA or SRA for individual records.

It doesn't hurt to try!
