Granted you have more vibration in the speaker box than out. But your acoustic space is also a speaker box of sorts. A passive device in line has signal running thru it will also corrupt the signal with its own material resonance. Devices that are highly damped actually store much energy over a longer time frame so they also needed to be mechanically grounded doesn't matter if its in a cabinet or not.Tom
