Speaker Stands Filled With Kitty Litter? TRUE???

Of all the silly things I have heard. Stands are to elevate the speakers to the right height and angle them for time alignment. The speaker weights way more than the stand. Adding mass means nothing. But if you are going to use kitty liter I suggest you weight till it is loaded with urine. The smell will make it sound better.

Yes, the speakers can outweigh some stands, and that in itself can be a problem, making the whole assembly top heavy. Using sand or kitty litter to fill voids in a stand can add weight and help to damp any resonances the stand may have. I bought some cheap stands last year that used aluminum tubes on glass plates, with long bolts going down the middle of the tubes to hold everything together. The first few minutes of listening with my speakers on them I could hear a glaring tone. A tap on the aluminum tubes revealed that they were resonant at the tone I was hearing. Touching them I could feel  the vibration. Filling those tubes with kitty litter (unused) completely solved the problem!

Expanding foam.

Don’t tap on them whilst music is playing.

Obviously. But isn’t that a test as to an indication of the mechanical transmission of sound through the support?
