There are numerous dampening devices on the market that are supposed to inhibit low frequency transmission from speakers to whatever they are sitting on like a shelf or the top of a desk. I have some of the Auralex foam wedges underneath my near field monitors that sit on top of my desk. They may help, slightly, to keep the desk from resonating but not enough to warrant their cost. Mine came with my monitors and I bought them used so they didn't cost me anything extra.
I know the commonly agreed upon solution is to use stands that hold the enclosures up off the surface. That is all well and good but in order for me to do that it means I am going to have to fabricate the stands because of space limitations that I have in my room. So, I was thinking about other options that may help decouple the speakers from my desktop.
In the arena of acoustics the best way to keep low frequencies isolated and decoupled from one room to another is mass. There's no substitute for that. The next best way is to have a confined air space between two air-tight boundary layers. I was thinking about how I could use an air space to decouple my near fields from the desktop and came up with a unorthodox solution that seems to be very effective. Bubble wrap.
I used some of the bubble wrap that has the 1" bubbles. I folded a sheet in half and sat the foam Auralex wedges on top of it then place my speakers on top of that. I could feel a noticeable difference in the sympathetic vibrations on my desk. If I get a wild hair I need to do some more scientific measurements using an oscillator and a dB meter but I did do a comparison with the same music, at the same level, with and without, the bubble wrap and could feel a substantial difference in the vibration in the top of my desk.
I'm thinking that I may even be able to compound the effectiveness by employing multiple layers of bubble wrap with a piece of wood between them. That would keep the speakers from getting teetery and add more of an air space.
It's definitely not high-tech and it looks kind of silly but, I'm not really about that. I'm all about what works and what doesn't. If I cut some wood for dividers I could conceal the bubble wrap a little by making it a little smaller than the wood platforms.
