My bookshelf speakers sit on top of a solid TV console, with their front sticking out the edge of the console to at least somewhat mitigate early reflections from the console top. They are not fixed in their place and with enough force you could slide them in any direction. They weigh about 30 lbs each. I don't hear any noise, rumble, or resonances from the speakers or the furniture. Should I expect to notice any improvement in sound by somehow anchoring them in place? The internet is full of anecdotes of "night and day" differences thanks to this or that method. But I would much rather learn of an analytic argument for or against it.
What prompted this inquiry is that the other day I read about using Blu Tack underneath the speakers. Since I had some Blu Tack lying around I figured I would give it a shot. To my surprise there was a marked improvement in the lower frequencies. Fearing the potential damage from long term use of Blu Tack, I had to remove it, after which I perceive that the improvement in the lower frequencies has disappeared. However, confounding this was that to mount the Blu Tack, I had to move the speakers, and then redo the measurement and bass management (DSP). So I don't know to which of the factors to attribute the effect: rearrangement, different EQ, or subjective bias.
As a last resort I could of course repeat the experiment, then again, instead of reinventing the wheel I feel I should rely on the knowledge and experience of the experts here. So I'm all ears
