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.
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?
